This document describes ValueRAM's 64M x 64-bit (512MB) CL3 SDRAM (SynchronousDRAM) PC133 DIMM module. The components on this module include sixteen32M x 8-bit (8M x 8-bit x 4 Bank ) PC133 SDRAM in TSOP packages. This 168-pin DIMMuses gold contact fingers and requires +3.3V. The electrical and mechanical specificationsare as follows:
