Memory Module Specification KVR400X64C3AK2/1G 1GB (512MB 64M x 64-Bit x 2 pcs.) DDR400 CL3 184-Pin DIMM Kit DESCRIPTION: ValueRAM's KVR400X64C3AK2/1G is a kit of two 64M x 64-bit (512MB) CL3 DDR400 SDRAM (Synchronous DRAM) memory modules. Total kit capacity is 1GB. The components on each module include eight 64M x 8-bit SDRAMs in TSOP packages. Each 184-pin DIMM 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 Power UL Rating
5ns (min.) / 10ns (max.) 55ns (min.) 70ns (min.) 40ns (min.) / 70,000ns (max.) +2.6V (+/- .1V) 2.184 W (operating) 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.
