Memory Module Specification
DESCRIPTION:
This document describes ValueRAM's 128M x 72-bit (1024MB) CL2.5 SDRAM (Synchro-
nous DRAM) Registered low profile DDR266 ECC memory module. The components on
this module include eighteen stacked 128M x 4-bit, 133MHz, 7.5ns, CL2.5 SDRAM and
three 16-bit drivers in TSSOP packages. This 184-pin DIMM uses gold contact fingers and
requires +2.5V. The electrical and mechanical specifications are as follows:
