Memory Module Specification
KVR333X64C25/1G
1GB 128M x 64-Bit DDR333
CL2.5 184-Pin DIMM
DESCRIPTION:
This document describes ValueRAM's 128M x 64-bit (1GB) DDR333 CL2.5 SDRAM
(Synchronous DRAM) memory module. The components on this module include sixteen
64M x 8-bit (16M 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:
