DESCRIPTION
The W3EG64255S is a 2x128Mx64 Double Data Rate
SDRAM memory module based on 512Mb DDR SDRAM
component. The module consists of sixteen 256Mx4
stacks, in 66 pin TSOP 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.
