DESCRIPTION
The WV3EG232M64EFSU is a 2x32Mx64 Double Data
Rate SDRAM memory module based on 256Mb DDR
SDRAM components. The module consists of sixteen
32Mx8 4 banks DDR SDRAMs in FBGA 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.
