Memory Module Specification
DESCRIPTION:
This document describes ValueRAM's 256M x 72-bit (2GB) DDR2-533 CL4 SDRAM (Syn-
chronous DRAM) ECC memory module. The components on this module include eighteen
128M x 8-bit (32M 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 specifica-
tions are as follows:
