Back to Basics: Jitter
A look at some of the tools built into modern digital oscilloscopes for jitter measurement and analysis.
“The nerd trigger was going to take forever to complete, but I figured we could create very similar functionality using the scope’s mask test infrastructure,” Genther said. “We could qualify acquisitions with mask testing and use that feature to push the button for him.” Mask testing shows all the waveforms that fail or exceed the limits of the mask. Genther’s brainstorm was to ignore all the waveforms that fail and just display the ones that do meet the mask limits. This process could happen behind the scenes, using digital technology to accomplish what the customer was doing manually.
CHAMPIONING THE IDEA Coming up with the idea to use a reverse mask test to achieve an easier version of the trigger was just the first step in the process of bringing it to market. Next, Genther had to convince his boss and teammates the project was worth pursuing.

BACK TO BASICS: JITTER David Maliniak Technical Marketing Communication Specialist Teledyne LeCroy
Anyone working in applications that involve digital data, clocks, and serial data in general will eventually bump up against issues concerning jitter. Jitter is a subject of keen interest to every strata of the electronics industry. Chip makers, board integrators, system integrators, you name it: Everybody wants, and needs, to come to terms with jitter. It impacts reliability, manufacturability, and cost at all levels. And, of course, it’s of keen interest to purveyors of test instruments, including us here at Teledyne LeCroy. In this first post of a projected series on jitter, we’ll look at some of the tools built into modern digital oscilloscopes for jitter measurement and analysis.
There are a number of measurement and analysis techniques one can turn to for quantifying and estimating jitter. Among them are: Histograms Measurement track Time Interval Error (TIE) Jitter breakdown and extrapolation Persistence display of jitter A traditional means of investigating a signal for jitter is to use the oscilloscope’s persistence display mode (Figure 2). It’s relatively easy to set up and get a quick eyeball estimate of total jitter. However, it’s not a method you’d use for serious diagnostics. The results are skewed by any trigger jitter that is present, and it’s also subject to human interpretation.
Figure 1: Jitter is short-term variation of a signal with respect to its ideal position in time
What’s all this “jitter” stuff, anyhow? A broad definition is “the short-term variations of a signal with respect to its ideal position in time.” Jitter can manifest as instability in signal period, frequency, phase, duty cycle, or other timing characteristics. It’s of interest from pulse to pulse, over many consecutive pulses, or as a longer-term variation. Figure 2: Persistence display can serve for a quick eyeball estimate of total jitter in a signal
TECH ARTICLE Some of the persistence analysis tools one finds in some Teledyne LeCroy oscilloscopes include: Ptrace mean: Generates a mean waveform from a persistence map Phistogram: Provides a histogram of a vertical or horizontal slice through a persistence map Ptrace range: Generates a waveform with a vertical width derived from a population range (estimate of confidence interval) of a persistence map Ptrace sigma: Generates a waveform with a width derived from the sigma of a persistence map. A broad range of clock and timing measurement parameters are available on most digital oscilloscopes. These include items such as: Hold time: Time from the clock edge to the data edge Setup time: Time from the data edge to the clock edge Skew: Time of Clock1 edge minus time of nearest Clock2 edge Dperiod@level: Adjacent cycle deviation (cycle-tocycle jitter) of each cycle in a waveform Dwidth@level: Difference of adjacent width above or below a specified level Duty@level: Percent of period for which data are above or below a specified level
Edge@level: Number of edges in a waveform Freq@level: Frequency at a specific level and slope for every cycle in a waveform Period@level: Period at a specific level and slope for every cycle in a waveform TIE@level: Difference between the measured times of crossing a given slope and level and the ideal expected time Width@level: Width measured at a specific level Half period: Half period of a waveform dVdt: Local slope or â€œslewâ€? rate Bit rate: Bit rate of a serial data stream Time Interval Error To look at one of these parameters a little closer, TIE@ level, or Time Interval Error, is the difference between the measured clock edge and the ideal clock edge locations (Figure 3). Basically, TIE is the instantaneous phase of the signal. References can be chosen from a standard telecom frequency or set to a user-defined value. TIE can be plotted versus time or unit intervals (UIs), the latter being the period of time corresponding to one cycle of a given frequency. A valuable tool is tracking of measurements, such as period, frequency, width, or duty cycle, to get a handle on how these measurements might be changing over time. Further, there is the ability to take a statistical view of jitter, which affords more reliable measurements thanks to the acquisition of more data.

DELIVERS POWER TO AMAZE Founded in 1957 by eight Shockley Semiconductor defectors, Fairchild Semiconductor pioneered the chip manufacturing industry and established the successful Silicon Valley start-up model still thriving today. Fueled by a shared goal, intellectual deftness, and an unrelenting spirit, the Shockley “treacherous eight” quickly grew Fairchild into a semiconductor industry leader, and by 1960, it was an incubator for Silicon Valley startups, such as AMD and Intel. Today, after a storied path, Fairchild 2.0 has emerged. By combining Fairchild’s rich history of successes with the spirit that ignited the company over 50 years ago, Fairchild 2.0 promises to drive innovation well into the future.
FRESH. FOCUSED. FAIRCHILD. Visit: eeweb.com
PULSE FAIRCHILD 2.0 For Fairchild, it has always been about the customer. The company’s commitment to its customers’ continued success has long served as the impetus behind the design of its technologies. The emphasis on quality improves the efficiency of home appliances and industrial products, and enables manufacturers of mobile devices to deliver innovative new features. But in the 50 years Fairchild has been serving its customers, the challenges facing engineers have evolved significantly. As Sajal Sahay, Vice President of Worldwide Corporate Marketing at Fairchild Semiconductor told EEWeb, “The two key things I keep hearing from our customers is that there is too much new information coming to them all the time, and that time to market is getting smaller and smaller. Engineers are always stressed to know more than what they do, mixed with the stress to get things done in record time.” Fairchild is well acquainted with the challenges facing its customers and recognizes that upholding an advantage in a highly competitive industry comes down to finding ways to help their
“As a company, we are centered on one simple goal: to make us the best company to work with as a design engineer in the power management field.”
customers work faster, smarter, and cheaper. The launch of Fairchild 2.0 is testimony of their efforts and of Fairchild’s long term commitment to its customers. “Our aspiration is to be transformative going forward,” Sahay said. “We’re focusing on individual products, expertise in design, expertise in pain-point resolution, and supply chain efficiency. As a company, we are centered on one simple goal: to make us the best company to work with as a design engineer in the power management field.” The tenets underlying Fairchild 2.0 hearken back to the company’s roots. The founders derided the prevalence of hierarchically structured companies common in the ‘50s and instead sought to create a company that took risks, fostered creativity, and rewarded contributions. The egalitarian culture pioneered by Fairchild— and now ubiquitous throughout Silicon Valley—is fundamental to Fairchild’s renewal. Fairchild 2.0, as Sahay expressed, “Is not only about financial gain. Financial gain is a byproduct of doing what’s right and making the world better. We’re bringing back what made the company great.”
THE POWER TO AMAZE With Fairchild 2.0, Fairchild has refocused the company’s attention on the customer and the accompanying launch of their new tagline that aptly characterizes their promise to truly deliver the Power to Amaze. As Sahay told EEWeb, “’Power’ refers to our focus on power management, empowering our people, and having the power to take care of our customers. It’s about giving laser focus on the area the company excels in and it also galvanizes our entire organization to put the customer first. ‘Amaze’ stands for going above and beyond and making customers very delighted in the service they get. We’re not going to be happy with simply supplying products.”
“Financial gain is a byproduct of doing what’s right and making the world better. We’re bringing back what made the company great.”
Accompanying the reincarnation of Fairchild is a new logo. The debut of their new logo differentiates Fairchild 2.0 from its predecessor as a semiconductor-centric company and reinforces their dedication to supplying their customers with amazing products, design expertise, logistics, and service. The old Fairchild logo had the two bars on top with the word “Semiconductor” below—the two bars were meant to be the first wafer. “What we’ve done with the new logo is made it cleaner,” Sahay explained. “We’ve taken the word ‘Semiconductor’ out because we are much more than a semiconductor component seller, we’re about providing comprehensive design solutions to our customers. We’ve also made the two red bars much wider and leaning forward. The intent here is to build from the past and actually drive towards the future.”
MEETING THE POWER DEMANDS OF THE FUTURE The power semiconductor industry has been growing two to three percent annually and is projected to explode into a 40 billion dollar business by 2016. Driving this exponential growth is the global demand for products that increasingly require more energy. Drawing upon its deep portfolio of products and legacy of expertise, Fairchild 2.0 is poised to meet the needs of its customers in terms of products and support. “We have expertise in multiple key markets,” Sahay explained. “We have expertise in mobile, cloud storage, industrial, and automotive. Our key promise to the customer is to offer them a breadth of power products from super low voltages to super high voltages.” However, supporting customers goes beyond just selling innovative products. To complement their vast product line, Faichild 2.0 will also offer designers ample support such as power design centers, product seminars, and online design and educational tools that will enable customers to solve challenges and speed up their time to market. Additionally, customers can be assured supply chain excellence. “Our supply lead time has decreased significantly from where it was twelve months ago,” Sahay said. “And our ontime delivery is best in class.” As a global company, Fairchild 2.0 is well suited to meet the power demands of the future. With 27 sales offices, five worldwide distributers, five global distribution centers, and 100 shipping lanes, combined with global power resource centers, Fairchild 2.0 customers can expect to be amazed.

INTRODUCING THE TIVA C SERIES CONNECTED LAUNCHPAD The IoT, combined with the cloud, has the potential to dramatically magnify the efficiency of appliances and embedded systems worldwide. But up until now, creating systems and developing applications that can communicate with one another has proven to be a non-trivial task. The recent announcement of TI’s Tiva C Series Connected LaunchPad has eliminated many of the obstacles that have stifled the development of IoT applications and offers everyone from the hobbyist to the professional engineer an easy (and low-cost) means to start developing applications that would have been inconceivable just a few years ago. EEWeb spoke with Joe Folkens, Product Marketing Engineer, Tiva C Series MCUs at TI, about the benefits of their newest LaunchPad device. “Based on the Tiva C Series TM4C1294NCPDT MCU, the Tiva C Series Connected LaunchPad will enable the IoT designs to get the desired results.” Engineers are still trying to determine what the IoT will actually be, meaning that a certain amount of flexibility is needed when developing these devices.
TI’s latest LaunchPad is the first in TI’s MCU LaunchPad and BoosterPack ecosystem to connect the user to the cloud right out of the box. Affordable and easy to use, the Tiva C Series Connected LaunchPad offers multi-type connectivity to all the interfaces on the board and allows embedded control to be extended through the cloud. “The kit comes with access to a cloud-based scale of technology from a third party partner named Exosite,” Folkens explained. “This allows the user to connect to and remotely interact with the Connected LaunchPad applications through embedded software operating on the board. It actually allows the user to essentially interact with the website or browser and other applications that operate on the Connected LaunchPad.”
TECH ARTICLE THE DETAILS The Tiva C Series LaunchPad includes a TM4C1294NCPDTI MCU with a 120 MHz ARM CortexM4F CPU, 1 MB Flash 256KB SRAM, and 6KB EEPROM. When it comes to connectivity, this Tiva C MCU integrates 10/100 Ethernet (both MAC and PHY), 8 x 32-bit (16 x 16-bit) timers, 10 x I2C, 8 x UART, 4 x QSPI, 2 x CAN, EPI, USB, and 2 x 12-bit ADCs. An IO connection grid provides access to the MCUs IO pins and the ability to interface to external circuitry, breadboards, and custom baseboards. Meanwhile, the RJ45 Ethernet jack, USB Host/Device Port, combined with user buttons and LEDs, make the Tiva C Series Connected LaunchPad an easy to use, versatile development platform. The feature-rich Tiva C Series LaunchPad makes it an ideal choice for the development of IoT applications. As Folkens told EEWeb, “The IoT application comes already pre-programmed on the board, which gives access to scalable, cloud-based solutions from Exosite. For a free software package, we have TivaWare, which is a very extensive, mature software base that has been developed over many years giving a strong foundation so users can focus on building their
value-add rather than spending the time getting the basic functions to work.” The Tiva C Series Connected LaunchPad comes with an integrated USB-powered, in-circuit, debug interface (ICDI) supported by the prior generation TM4C123 microcontroller also included on the board. BoosterPack plug-in modules that fit on top or bottom of the LauchPad using a standardized connector allow developers to expand the capabilities of the LaunchPad to explore different applications. The BoosterPacks are available from TI, third parties, as well as the community, and include functions such as capacitive touch, wireless communication, LCD panels, sensor readings, LED lighting control and more. The connectors that TI is using are stackable and dual-gender, which means that the board has a back side for the female version of the header so you can plug-on to something else as well. “Theoretically, you can plug-in four different booster packs into the two headers,” Folkens explained, “but you must also consider that there is shared GPIO or functionality so you may have to make some minor modifications in your firmware. Nevertheless, it is there for you to use,” Folkens said.
“Affordable and easy to use, the Tiva C Series Connected LaunchPad offers multi-type connectivity to all the interfaces on the board and allows embedded control to be extended through the cloud.”
READY TO LAUNCH For the launch of the Tiva C Series Connected LaunchPad, TI has partnered with Exosite, mentioned briefly above, to provide easy access to the LaunchPad from the Internet. The LaunchPad takes about 10 minutes to set up and you can immediately interact with it across the Internet and do things like turn an LED on and off remotely from the website and see the reported temperature as well. It can also display approximate geographic location based on the assigned IP address and display a map of all other connected LaunchPad owners if they are active and plugged-in to Exosite. “In addition, it supports a basic game by enabling someone to interface to the Connected LaunchPad through a serial port from a terminal while someone else is playing with them through their browser. It is basically showing how you can interact remotely with this product and a user even if you are across the globe,” Folkens explained.
START DEVELOPING The Tiva C Series Connected LaunchPad is shipping now and the price is right; at $19.99 USD, it is less than half the price of other Ethernet-ready kits. The LaunchPad comes complete with quick start and user guides, and ample online support to ensure developers of all backgrounds are well equipped to begin creating cloud-based applications. “We have assembled an online support team to monitor the Engineering-to-Engineering (or E2E) Community,” Folkens said. “Along with this, you also got a free Code Composer Studio Integrated Development Environment, which allows developers to use the full capability. We also support other tool chains like Keil, IAR and Mentor Embedded.
Affordable, versatile, and easy to use, the Tiva Series Connected LaunchPad is well suited for a broad audience and promises to facilitate the expansion of ingenious IoT applications in the cloud. As Folkens concluded, “The target audiences actually are the hobbyists, students and professional engineers. A better way of looking at it is that we are targeting people with innovative ideas and trying to help them get those ideas launched into the cloud.”
Scott Genther Key inventor of Agilent Zone Trigger
How Product Innovation Happens: The Origin of Agilent’s Oscilloscope Trigger Engineers who use oscilloscopes are typically focused on solving problems and looking for ways to make better products. It turns out that engineers who design oscilloscopes are essentially doing the same thing. More than a decade ago, an Agilent Technologies oscilloscope designer named Scott Genther was getting ready to launch a massive, multiyear project to design a new chip for an advanced algorithmic oscilloscope trigger—affectionately known in the Agilent R&D lab as the “nerd trigger.” Before the project even got off the ground, he came up with a remarkably simple idea for a trigger that ultimately redefined how engineers use Agilent oscilloscopes. Where do innovative ideas like Genther’s come from? And how do you get from the original spark of inspiration to its implementation in an innovative product? Genther’s story sheds light on how product innovations happen.
CONNECTING WITH CUSTOMER FRUSTRATIONS In a quest to define the features he needed to include in his trigger ASIC, Genther visited oscilloscope customers to understand how they used triggering and what stumbling blocks they faced. “In the lab here at Agilent, R&D engineers know how to use all the triggers on their scopes,” said Genther. “But I quickly discovered our customers don’t. They don’t like thinking about triggers. A lot of customers just pick a mode and turn the knob to clean up the display. They don’t have time to sit down and think about it.” The first customer Genther visited was having trouble defining a trigger to capture the clock edge reads he wanted to see. In frustration, he jabbed a finger at the screen and wondered why he couldn’t just click on a piece of a waveform and get what he wanted. At the time, Genther just assumed it was impossible. The second customer Genther visited had come back from lunch and discovered a bad trace on his oscilloscope screen. The scope’s infinite persistence showed him something had happened when he was away. To figure out what caused it, he wanted to get a view of the trace by itself so he could correlate it to activity on other channels. The customer had been doing single-shot acquisitions for days trying to locate the infrequently occurring glitch. He pushed the “single” button over and over and still couldn’t locate the problem. Watching the engineer laboriously pecking away at the button, Genther experienced his big “aha” moment. He could see that pressing the “single” button a million times is a painful way to find a one-in-a-million glitch, and he realized he could make both customers’ jobs easier using Agilent’s existing oscilloscope technology.
“The nerd trigger was going to take forever to complete, but I figured we could create very similar functionality using the scope’s mask test infrastructure,” Genther said. “We could qualify acquisitions with mask testing and use that feature to push the button for him.” Mask testing shows all the waveforms that fail or exceed the limits of the mask. Genther’s brainstorm was to ignore all the waveforms that fail and just display the ones that do meet the mask limits. This process could happen behind the scenes, using digital technology to accomplish what the customer was doing manually. CHAMPIONING THE IDEA Coming up with the idea to use a reverse mask test to achieve an easier version of the trigger was just the first step in the process of bringing it to market. Next, Genther had to convince his boss and teammates the project was worth pursuing.

PULSE mockup to his desk. “I used it on the spot,” he said. “It was clear to me this was going to be a useful feature.” “Once you have a mockup, it is an easier sell than if you are just trying to sell an idea,” said Genther. “You can say, ‘Come on over here and take a look,’ and immediately show it to your boss or teammates.” At the last minute, the team agreed to use the new feature in the original release of the InfiniiScan event identification software package for Agilent DSO80000B Series Infiniium oscilloscopes, introduced in February 2006. The software is designed to help engineers identify signal integrity issues in their electronic designs more easily. Before the feature could be released, the team had to figure out what to call it. “We had a huge debate about whether it was OK to call it a trigger,” said Genther. “Technically, it is a mask, not a trigger, and we didn’t want to confuse customers.”
Figure 2 & 3 Demonstrate how thw zone trigger was eventually implemented with a touch screen. Touch the signal of interest and then select must intersect the scope then displays only the signal of interest.
He got software designers and hardware designers together in the same room and lobbied for his idea. He stressed that the new feature required no new technology to be developed. “We already had the infrastructure in place for qualified triggers, so I had to convince the team we could use that infrastructure to address a user-interface problem,” said Genther. The breakthrough came when one of the software developers on his team agreed to create a mockup of the zone trigger. Genther was doing some troubleshooting, looking for bad signals on a bus, when the software developer brought the completed
The team did some research and discovered that most engineers think of triggers as “anything that gives them the picture they want.” The team ultimately decided to call it a software trigger. “It ended up being the star feature of the InfiniiScan software package,” Genther said. MOVING BEYOND SOFTWARE The software trigger’s success as part of the InfiniiScan package made the next step easy: incorporating the feature directly in an oscilloscope. When the scope designers were defining the high-performance Infiniium 90000 Series oscilloscopes, the team didn’t hesitate to include it. In fact, this technology enabled the world’s first three-stage triggering system, where the first two stages are hardware-based triggers and the third stage is a software trigger. At that point, advanced trigger features in general, and the software trigger in particular, were incorporated only in high-end oscilloscopes. Several years later, Agilent’s oscilloscope team designed a new chip that dramatically changed
TECH ARTICLE the game by allowing engineers to control and use a scope’s features via a capacitive touch screen. Shown in Figure 4 the new “MegaZoom IV” chip enabled scopes with extremely fast update rates -- a million waveforms per second – and it implemented mask test and Genther’s inverse mask test, rebranded as InfiniiScan Zone triggering, as hardware features. Implementing the zone triggering functionality using high-speed digital ASIC hardware made it much faster. It could capture 1,000,000 waveforms per second, which made it much more likely that engineers would be able to see the glitch or anomaly they were looking for. The InfiniiScan Zone trigger, even when it is implemented in hardware, can produce the signal of interest only as fast as the oscilloscope can capture it. The chip made its debut in the InfiniiVision 4000 X-Series oscilloscopes, introduced November 13, 2012, and it revolutionized how engineers use oscilloscopes. The combination of the capacitive touch screen capability and the hardwarebased InfiniiScan Zone trigger makes it easy to trigger on signals by drawing a box around the
ones of interest. The 4000 X-Series oscilloscope then creates the trigger based on the mask. “It would be very clumsy to try to draw a box by turning knobs and pushing buttons,” Genther said. “With the touch screen, if you can see it, you can trigger on it simply by pointing at it- exactly what the engineer from my original customer visit was asking for. Using this method, you can easily isolate things you see only infrequently. It is the combination of these features that sets the InfiniiVision 4000 X-Series apart. The hardware-based InfiniiScan Zone trigger and capacitive touch screen are the most obvious innovations, but without the fast update rate of the MegaZoom IV ASIC, you wouldn’t even know the infrequent events are there. “Any engineer who does digital design will appreciate the InfiniiScan Zone touch trigger,” said Genther. “The classic case is working on memory devices. You have a clock, and you have reads and writes on top of each other. It is a mess. The bus goes one way with the reads and the other way with the writes, and the timing is completely different. You are probing the bus and seeing both. So you draw a box around something that happens only with the writes, and boom—you have just the writes.” MEANINGFUL INNOVATIONS

The most important product innovations happen when designers respond to customer frustrations and work toward ways to help them solve their problems more easily. “With zone triggering, it was like figuring out we could slice the bread before we sell it to customers so they don’t have to slice it themselves,” said Genther. “The whole thing was about the user interface. The result is that customers no longer have to think about how to set up an oscilloscope trigger.”
Figure 5: InfiniiVision 4000 X-Series Oscilloscope
Combing the trigger innovation with the MegaZoom IV chip takes it to the next level. Now Agilent’s customers can see their glitches and trigger on them without needing to understand nerdy triggering concepts.

Raising the Bar:
Crossbar’s Entirely New Type of Memory Crossbar is a groundbreaking memory technology company based in Santa Clara, California. Crossbar turned heads last year when they unveiled a new category of high performance resistive RAM (RRAM) technology that can scale up to 1 terabyte on a chip the size of a postage stamp. This highly scalable technology performs around 20x faster than today’s NAND Flash memory and has 10x the endurance at half the die size. With these unparalleled specifications, Crossbar’s technology will enable the next generation of highperforming electronic devices. EEWeb spoke with George Minassian, CEO of Crossbar, about the current limitations in the Flash memory industry, how the company plans to overcome them, and how their new RRAM technology will redefine the industry as we know it.
George Minassian, CEO of Crossbar
Could you tell us about how you came to co-found Crossbar? I started at AMD where I spent time working on communication devices, microprocessors and system architectures. I then joined the Flash JV division of AMD and Fujitsu, where I worked in strategic marketing. While I was there, I heard about this new technology from a client and got very excited about it. The more I learned about it, the more excited I became. The technology was produced by a team of researchers at the University of Michigan, and they had already passed a number of milestones needed to achieve credibility. After I had a chance to see the technology up close, I got involved with the team, which included financial and corporate support from Kleiner Perkins Caufield & Byers, a Bay Area venture firm. Together we knew we had to start a company around the underlying technology. I brought in a few other colleagues and that is how we founded Crossbar.
How important was that initial phase in terms of gaining investor interest? The initial part of starting a company like this is getting from lab to fab. When you set up a lab, you take the best of the “recipes” for your technology because everything is available to you. The problem is, the toolset for each of the “recipes” can be slightly different, and some might not be manufacturable. So, using commercially available fabrication tools, we tried to duplicate the outcomes. In the first couple of runs, we discovered some things weren’t working the way they should. We spent about a year fine-tuning, taking measurements and making accurate adjustments before we got to a point where the array was fully functioning. After that, we used CMOS from TSMC, put the array on top of it and put the rest of the pieces together – all over the course of about three years.
CROSSBAR’S SIMPLE AND VERY SCALABLE MEMORY CELL STRUCTURE ENABLES AN ENTIRELY NEW CLASS OF 3D RRAM, WHICH CAN BE EASILY INCORPORATED INTO THE BACK END OF ANY STANDARD CMOS MANUFACTURING FAB.
INTERVIEW What is Crossbar currently offering as a company? We are providing licensable IP technology for embedded to start with. We are also transferring the existing technologies we have with our pilot line fab into our commercial fabs. As we are developing the sub-20nm arrays and characterizing those, we are also preparing our 55nm and 40nm technology for production. When the transfer is completed, over the next nine months, the fab will be qualified to accept customers for business. Our product is very unique—it’s CMOS compatible, and it has embedded capabilities in terms of random access and CMOS compatible process. It is also suited to handle higher densities because the cell itself is extremely small. It has MLC and stacking capabilities. Stacking is very simple—each layer just repeats itself without the complexity of 3D NAND implementations.
Given all of that, we can do very high-density devices in a 40nm or even 65nm technology nodes, meaning it will cover a wide range of technologies. Of course, the smaller the node, the denser the device can get. The interesting part is that all of these types of technologies are being transferred to our fab. When you transfer this to a fab, you have the opportunity to do embedded, standalone NOR, or standalone NAND. For us, the complexity of the controller is the only thing that makes it one or the other. In terms of Flash today, you need to change the entire factory and manufacturing process to go from one to the other. In our case, you just have to change the controller.
What are the current limitations of the standard non-volatile Flash memory and how does your technology differ? Current Flash is based on the presence of electrons to detect the logic. For example, in 30nm technology, you have a couple dozen electrons for a 1-volt differential. When you shrink your device, the number of electrons becomes fewer and fewer. At some point, for very small nodes, you have to detect ten to 20 electrons to know if the device is ON or OFF. What we have witnessed is, as theses nodes get smaller and the number of electrons diminishes, the controller logic needs to become a lot more sophisticated. You put a lot of these cells next to each other, then test them by leaving them in your car to see if the electrons behave differently at higher temperatures. This is especially true for parts destined for commercial devices. Those elements make the detectors even more sensitive, which is why NAND and NOR are having difficulty.
Crossbar’s scalable cell structure
“THE PHYSICS ACTUALLY WORKS IN OUR FAVOR; AS YOU SHRINK THE DEVICE, THE PERFORMANCE GETS BETTER.” In our case, our design is based on a metal filament. We have a layer of isolated silicon and we drive metal through it by applying some polarities across that sandwich of silicon layers. Once the metal goes inside, you make a connection. This is based on the ions of metal being forced into a non-conducting layer. There are three layers in total: one conducting layer at the bottom, one non-conducting in the center and the metal on the top. We saw how the physics works against NAND, because of the diminishing number of electrons at the smaller geometries. Compared to NAND, our technology differs because of a very large ON current to OFF current ration which makes the detection of ON and OFF states much simpler. For us when the device is ON, that current is a function of the filament and, regardless of the size of the device, it stays the same. The current on the bottom of the equation—which is the OFF state—is when there are no filaments in the device. This current is caused by the leakage in the device. As you shrink the device, that leakage current gets smaller and smaller. As a result the ON/OFF ratio for us becomes larger and the ability to detect when the device is ON, versus when it is OFF, becomes easier. The physics actually work in our favor; as you shrink the device, the performance gets better. As a consequence of that, the 20nm small arrays we are doing in our R&D fab start with four levels per cell. We have tested tens of thousands of cycles without any difficulty.
For investors, a technology like this would seem very attractive. What’s it going to take for this technology to become ubiquitous? The steps we are taking right now lead toward mainstream adoption. The commercialization process involves bringing our existing technology to a fab and repeating the same process at 40nm and 50nm technology nodes, which we are doing right now. Once we have that completed we will start the embedded licensing business, as well as the standalone code and data business. We have done transfers from fabs multiple times—starting from the University to our fab, and then from our fab to several commercial grade fabs. Each time we set up, we learn how quickly we can do this. Each time, within three months of transferring, we had our arrays working. We now have to repeat the transfer again as we move to our new commercial fab, and we’re confident it can be done. This means within nine months we’ll be ready for a qualification cycle, and at that point, we’ll have customers coming in with their requirements.
Do you have any technology partners that you are working with to bring this to market? Crossbar has a complete technology, so in terms of partnerships, we are set. In fact, we already have about 45 issued patents for our technology, with another 55 pending. From a manufacturing standpoint and implementing at specific nodes, we’ll be partnering with large, commercial fab partners.
INTERVIEW What is Crossbar’s roadmap for competing with Flash technologies? There are several requirements to put our technology into a competitive position versus Flash. For our one terabyte devices, we will need a 20nm fab, and we will have had to perfect the stacking of MLC. Once we transfer the cells and arrays to a commercial fab, we can move from an embedded design to a standalone design. To do this, we will need to change the controller because standalone designs need to have different interfaces to the outside devices. Switching the controller from an embedded architecture, which uses someone else’s controller logic, to a standalone controller, is the biggest hurdle. The other requirement is moving from a 40nm node to a 28nm node. Currently, we plan to use a 55nm node, based on the toolsets available right now. After that, we will convert to a smaller node. Most of the 28nm fabs are in various stages of availability, but are ready to be introduced to a new technology. We expect it to take about two years to completely transfer our technology to a 28nm fab.
Could you talk about some of the non-volatile aspects of this memory? When it comes to Flash, there are several parameters that people use. The most critical parameters are voltage, current, endurance and temperature. For us, the voltages are all well below 5V because we are 100 percent CMOS and very close to 2V for read and write. The power has to be extremely low, and in our case, we are 20 times lower than anyone else. In terms of endurance, we are pushing 100,000 cycles.
What is Crossbar most excited about with this technology? We are a highly technical group, so we tend to get excited about the technology. But, we get even more excited about it when we meet with potential customers and we see they’re excited. We feel we are at the leading edge of a new memory landscape, and we strongly believe our technology will bring great improvements to current systems and will enable a new era of applications and products.

FAN23SV04T High ciency Buck Converter The FAN23SV04T High Efficiency Synchronous Buck Converter from Fairchild is designed to power DDR termination rails in applications such as servers, telecom hardware, game consoles, and notebooks. The device is suitable for any application requiring an efficient tracking converter capable of sourcing and sinking multiple amps of current.
Included Hardware Enable & Test Pins
FAN23SV04T Buck Converter
Transient Load Switches
PRODUCT OVERVIEW Tech Specs DDR4 requires a termination supply (VTT) to be half of VDDQ. This has typically been accomplished by generating VDDQ from the 12V supply and using a linear regulator, supplied by VDDQ, to generate VTT. This setup results in a VTT conversion efficiency of about 45%. The FAN23SV04T uses VDDQ as an input, but can be supplied from a separate rail; typically the same 12V rail that supplies the VDDQ regulator. This setup results in a VTT conversion efficiency of about 80%â€”a significant improvement over the linear regulator approach. The FAN23SV04T also integrates the 50% resistive divider network in the IC. This results in very tightly-matched resistors and eliminates the added footprint and cost of providing external high-precision resistors. If your design requires tracking at something other than 50% of your reference supply, it is possible to add external resistors to adjust the tracking ratio.
