The WED3DG6418S is a 16Mx64 Double Data Rate

SDRAM memory module based on 128Mb DDR

SDRAM component. 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.
