Memory Module Specification
KVR133X64C3Q/256
256MB 32M x 64-Bit PC133
CL3 168-Pin DIMM Module
DESCRIPTION:
This document describes ValueRAM's 32M x 64-bit (256MB) PC133 CL3 SDRAM (Synchronous DRAM) DIMM module. The components on this module include sixteen 16M x 8-bit (4M x 8-bit x 4 Bank) PC133 SDRAM in TSOP packages. This 168-pin DIMM uses gold contact fingers and requires +3.3V. The electrical and mechanical specifications are as follows:
FEATURES:
