256MB – 32Mx72 DDR SDRAM REGISTERED, w/PLL
DESCRIPTION
The W3EG7236S is a 32Mx72 Double Data Rate
SDRAM memory module based on 256Mb DDR
SDRAM component. The module consists of nine
32Mx8 DDR SDRAMs in 66 pin TSOP package
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 Lenths allow the
same device to be useful for a variety of high bandwidth,
high performance memory system applications.
* This product is under development, is not qualified or characterized and is subject to
change without notice.
