Memory Module Specification
DESCRIPTION:
This document describes ValueRAM's 32M x 72-bit (256MB) CL3 PC133 SDRAM (Syn-
chronous DRAM) ECC DIMM module. The components on this module include nine
32M x 8-bit (8M 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:
