DESCRIPTION
The WV3EG264M64EFSU is a 2x64Mx64 Double Data
Rate SDRAM memory module based on 512Mb DDR
SDRAM component. The module consists of sixteen
64Mx8 bit with 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.
