com DESCRIPTION The W3EG6464S is a 64Mx64 Double Data Rate SDRAM memory module based on 512Mb DDR SDRAM component.
The module consists of eight 64Mx8 DDR SDRAMs in 66 pin TSOP 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.
