Memory Module Specification KVR400X64SC3A/512 512MB 64M x 64-Bit DDR400 CL3 200-Pin SODIMM DESCRIPTION: This document describes ValueRAM's 64M x 64-bit (512MB) DDR400 CL3 SDRAM (Synchronous DRAM) memory module. The components on this module include eight 32M x 16-bit (8M x 16-bit x 4 Bank) DDR400 SDRAM in TSOP packages. This 200-pin SODIMM uses gold contact fingers and requires +2.6V. The electrical and mechanical specifications are as follows: FEATURES: Clock Cycle Time (tCK) Row Cycle Time (tRC) Refresh Row Cycle Time (tRFC) Row Active Time (tRAS) Single Power Supply of Operating (IDD0) UL Rating
6ns (min.) / 12ns (max.) 60ns (min.) 72ns (min.) 42ns (min.) / 70,000ns (max.) +2.6V (+/- .1V) 3.615 W 94 V - 0
Note: The module defined in this data sheet is one of several configurations available under this part number. While all configurations are compatible, the DRAM combination and/or the module height may vary from what is described here. However, in no configuration will the module height exceed 1.250" (31.75mm). 2.70 (67.60) 2.50 (63.60)
