Apacer DDR-400 1GB SO-DIMM 1GB DDR 400MHz memory module

DDR-400 1GB/SO-DIMM 184-pin/CAS 3-3-3/Bandwidth 3200MBps/Desktop DDR memory offers twice the data bandwidth of conventional PC100 or PC133 SDRAM, and is particularly well suited for high-performance servers and workstations, which need optimal CPU-memory performance. Double Data Rate (DDR) SDRAM is precisely what the name implies. A clock cycle can be represented as a square wave, with the rising edge defined as the transition from "0" to "1", and the falling edge as "1" to "0". In SDRAM, only one of these wave edges is used, but DDR SDRAM references both, effectively doubling the rate of data transmission.

The Module is DDR-400 CL3 Unbuffered Memory module. The Module density from 256MB to 1GB , it consists 32/64MX8 bit DDR-400 Synchronous DRAMs in TSOP II packages, Memory Module intented for mounting into 184-pin edge connector sockets. The electrical and mechanical specifications are as follows.
