DESCRIPTION
The W3EG264M72EFSU is a 2x64Mx72 Double Data
Rate SDRAM memory module based on 512Mb DDR
SDRAM components. The module consists of eighteen
64Mx8 DDR SDRAMs in FBGA 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 applications.
