Description

The W3EG264M72AFSR is a 2x64Mx72 Double Data Rate SDRAM memory module based on 256Mb DDR SDRAM components. The module consists of thirtysix 64Mx4, in FBGA packages 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 tions.
