Memory Module Specification KVR400D2R3/1G 1GB 128M x 72-Bit x DDR2-400 CL3 Registered 240-Pin ECC DIMM DESCRIPTION: This document describes ValueRAM's 128M x 72-bit (1GB) DDR2-400 CL3 SDRAM (Synchronous DRAM) registered ECC memory module.The components on this module include eighteen 128M x 4-bit (32M x 4-bit x 4 Bank) DDR2-400 SDRAM in FBGA packages. This 240-pin DIMM uses gold contact fingers and requires +1.8V. The electrical and mechanical specifications are as follows: FEATURES: Clock Cycle Time (tCK) CL=3 Row Cycle Time (tRC) Refresh to Active/Refresh Command Time (tRFC) Row Active Time (tRAS) Single Power Supply of Power UL Rating 5ns (min.) / 8ns (max.) 55ns (min.) 127.5ns 40ns (min.) / 70,000ns (max.) +1.8V (+/- .1V) 4.050 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). (Units = millimeters) Figure 1: KVR400D2R3/1G 240-Pin DIMM Document No. VALUERAM0359-001.B00 10/11/04
