512MB – 2x32Mx72 DDR SDRAM REGISTERED, w/PLL
DESCRIPTION
The W3EG7265S is a 2x32Mx72 Double Data Rate
SDRAM memory module based on 256Mb DDR SDRAM
components. The module consists of eighteen 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.
