DESCRIPTION:
This document describes ValueRAM's 128M x 72-bit 1GB (1024MB) DDR2-400 CL3
SDRAM (Synchronous DRAM) "single rank" registered ECC memory module. The compo-
nents 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:
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).
