DESCRIPTION The WV3EG64M64ETSU is a 64Mx64 Double Data Rate SDRAM memory module based on 512Mb DDR SDRAM ponents. The module consists of eight 64Mx8 DDR SDRAMs TSOP-II 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.
