Memory Module Specications
KVR266X64SC25/512
512MB 64M x 64-Bit DDR266
CL2.5 200-Pin SODIMM
DESCRIPTION
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
ngers and requires +2.5V. The electrical and mechanical
specications are as follows:
Note: The module dened in this data sheet is one of several congurations available under this part number. While all congurations are compatible, the DRAM
combination and/or the module height may vary from what is described here.
