DESCRIPTION The WED3DG6417S is a 16Mx64 Double Data Rate SDRAM memory module based on 128Mb DDR SDRAM ponent. The module consists of eight 16Mx8 DDR SDRAMs in 66 pin TSOP 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.
