DESCRIPTION
the W3EG72128S is a 2x64Mx72 Double data Rate
SDRAM memory module based on 512Mb DDR SDRAM
components. The module consists of eighteen 64Mx8
DDR SDRAMs in 66 pin TSOP packages mounted on a
184 pin FR4 substrate.
Synchronous design allows precisse 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.
