Memory Module Specification KVR400X64C3AK2/256 256MB (128MB 16M x 64-Bit x 2 pcs.) DDR400 CL3 184-Pin DIMM Kit DESCRIPTION: ValueRAM's KVR400X64C3K2/256 is a kit of two 16M x 64-bit (128MB) CL3 DDR400 SDRAM (Synchronous DRAM) memory modules. Total kit capacity is 256MB. The components on each module include four 16M x 16-bit (4M x 16-bit x 4 Bank) DDR400 SDRAM 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 (IDD0) UL Rating 5ns (min.) / 10ns (max.) 55ns (min.) 70ns (min.) 40ns (min.) / 70,000ns (max.) +2.6V (+/- .1V) 0.975 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. However, in no configuration will the module height exceed 1.250" (31.75mm).
