Description
The A-DATA DDR400 module for Notebook is a double data rate module composed of CMOS Double Data Rate SDRAMs in TSOP-II 400mil 66pin package and one 2Kbit EEPROM in 8pin TSSOP(TSOP) package on a 200pin glassûepoxy printed circuit board. 

The A-DATA DDR400 is a Dual In-line Memory Module and is intended for mounting onto 200-pins edge connector sockets. Synchronous design allows precise cycle control with the use of system clock. Data I/O transactions are possible on both edges of DQS. Range of operating frequencies programmable latencies and burst lengths allow the same device to be useful for a variety of high bandwidth high performance memory system applications.
