WED3EG72256SXX-JD3
2GB- 256Mx72, ECC, DDR SDRAM DIMM REGISTERED
MODULE
The WED3EG72256SXX-JD3 is a 256Mx72 Double
Data Rate SDRAM memory module based on 1
Gigabit DDR SDRAM components. The module
consists of eighteen, 256Mx4 DDR SDRAMs in 66
pin TSOP packages mounted on a 184 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.
