512MB 64M x 72-Bit DDR266 CL2.5

ECC Registered 184-Pin DIMM

DESCRIPTION:

This document describes ValueRAM's 64M x 72-bit (512MB) DDR266 CL2.5 SDRAM

(Synchronous DRAM) low-profile Registered ECC memory module. The components on

this module include eighteen 64M x 4-bit (16M x 4-bit x 4 Bank) DDR266 SDRAM in TSOP

packages. This 184-pin DIMM uses gold contact fingers and requires +2.5V. The electrical

and mechanical specifications are as follows:
