DESCRIPTION
The W3EG2128M72AFSR is a 2x128Mx72 Double Data
Rate SDRAM memory module based on 512Mb DDR
SDRAM components. The module consists of thirty six
128Mx4 components, 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 applications.
