DESCRIPTION
The WV3EG6434S is a 32Mx64 Double Data Rate SDRAM memory module based on 256Mb DDR SDRAM component. The module consists of eight 32Mx8 DDR SDRAMs in BGA package 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 Lenths allow the same device to be useful for a variety of high bandwidth, high performance memory system applications.
