This document describes ValueRAM’s 128M x 72-bit (1024MB), 
CAS Latency 2.5 SDRAM (Synchronous DRAM) DDR266 ECC 
memory module. The components on this module include eigh-
teen 64M x 8-bit (16M x 8-bit x 4 Bank / 133MHz, 7.5ns, CL2.5 
components) SDRAM in TSOP packages. This 184-pin DIMM 
uses gold contact fingers and requires +2.5V. The electrical and 
mechanical specifications are as follows:
