KVR333X64C25/512
512MB 64M x 64-Bit DDR333
CL2.5 184-Pin DIMM
DESCRIPTION:
This document describes ValueRAM's 64M x 64-bit (512MB) DDR333 CL2.5 SDRAM
(Synchronous DRAM) memory module. The components on this module include sixteen
32M x 8-bit (8M x 8-bit x 4 Bank) DDR333 SDRAM in TSOP packages. This 184-pin DIMM
uses gold contact fingers and requires +2.5V. The electrical and mechanical specifications
are as follows:
FEATURES:
