DESCRIPTION
The W3EG7218S is a 16Mx72 Double Data Rate
SDRAM memory module based on 128Mb DDR
SDRAM component. The module consists of nine
16Mx8 DDR SDRAMs in 66 pin TSOP package
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 Lenths allow the
same device to be useful for a variety of high bandwidth,
high performance memory system applications.
