DESCRIPTION:
This document describes ValueRAM's 32M x 72-bit (256MB) DDR2-400 CL3 SDRAM
(Synchronous DRAM) registered ECC memory module. The components on this module
include nine 32M x 8-bit DDR2-400 SDRAM in FBGA packages. This 244-pin MiniDIMM
uses gold contact fingers and requires +1.8V. The electrical and mechanical specifications
are as follows:
