Memory Module Specification
DESCRIPTION:
This document describes ValueRAM's 32M x 72-bit (256MB) CL4 DDR2-533 SDRAM
(Synchronous DRAM) ECC memory module. The components on this module include
nine 32M x 8-bit (8M x 8-bit x 4 Bank) DDR2-533 SDRAM in FBGA packages. This 240-
pin DIMM uses gold contact fingers and requires +1.8V. The electrical and mechanical
specifications are as follows:
