Memory Module Specification
DESCRIPTION:
This document describes ValueRAM's 32M x 64-bit (256MB) DDR2-400 CL3 SDRAM
(Synchronous DRAM) memory module. The components on this module include eight
32M x 8-bit (8M x 8-bit x 4 Bank) DDR2-400 SDRAM in FBGA packages. This 200-pin
SODIMM uses gold contact fingers and requires +1.8V. The electrical and mechanical
specifications are as follows:
