DESCRIPTION
The W3EG7266S is a 64Mx72 Double Data Rate
SDRAM memory module based on 512Mb DDR SDRAM
components. The module consists of nine 64Mx8 DDR
SDRAMs in 66 pin TSOP packages mounted on a 200
pin FR4 substrate.
Synchronous design allows precise cycle control with the
use of system clock. Data I/O transactions are possible
on both edges and Burst Lengths allow the same device to
be useful for a variety of high bandwidth, high performance
memory system ap pli ca ions.
