Memory Module Specification KVR400X64C3A/1G 1GB 128M x 64-Bit DDR400 CL3 184-Pin DIMM DESCRIPTION: This document describes ValueRAM's 128M x 64-bit (1GB) DDR400 CL3 SDRAM (Synchronous DRAM) memory module. The components on this module include sixteen 64M x 8-bit (16M x 8-bit x 4 Bank) DDR400 SDRAM in TSOP packages. This 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) Operating Temperature Storage Temperature UL Rating 5ns (min.) / 10ns (max.) 55ns (min.) 70ns (min.) 40ns (min.) / 70,000ns (max.) +2.6V (+/- .1V) 5.408 W (operating) 0o C to 70o C -55o C to +150o C 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).
