512MB – 2X32Mx72 DDR SDRAM UNBUFFERED
DESCRIPTION
The W3EG7262S 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 packages 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 Lengths allow the same device to be
useful for a variety of high bandwidth, high performance
memory system applications.
