256MB – 32Mx72 DDR SDRAM UNBUFFERED w/PLL
DESCRIPTION
The W3EG7232S is a 32Mx72 Double Data Rate
SDRAM memory module based on 256Mb DDR SDRAM
components. The module consists of nine 32Mx8 DDR
SDRAMs in 66 pin TSOP packages 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 Lengths allow the same device to be
useful for a variety of high bandwidth, high performance
memory system applications.
* This product is subject to change without notice.
