Memory Module Specification
KVR266X64SC25/512
512MB 64M x 64-Bit DDR266
DESCRIPTION:
CL2.5 200-Pin SODIMM
This document describes ValueRAM's 64M x 64-bit (512MB) CL2.5 SDRAM (Synchronous
DRAM) DDR266 memory module. The components on this module include sixteen
32M x 8-bit (8M x 8-bit x 4 Bank / 133MHz, 7.5ns, CL2.5) DDR266 SDRAM in uBGA
packages. This 200-pin DIMM uses gold contact fingers and requires +2.5V. The electrical
and mechanical specifications are as follows:
FEATURES:
