The W3EG72125S is a 2x64Mx72 Double Data Rate
SDRAM memory module based on 256Mb DDR SDRAM
components. The module consists of eighteen 2x64Mx4
stacked (36 components), in 66 pin TSOP package
mounted on a 184 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.
* This product is under development, is not qualified or characterized and is subject to
