DESCRIPTION
The W3EG72255S is a 2x128Mx72 Double Data Rate
SDRAM memory module based on 512Mb DDR SDRAM
components. The module consists of eighteen 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.
