1GB DDR400 SODIMM 200Pin Laptop Memory 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 glass–epoxy 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. •DLL aligns DQ and DQS transition with CK transition• Double-data-rate architecture• Bi-directional data strobe (DQS) • Differential clock inputs (CK and /CK)• Auto refresh and self refresh• 8192 refresh cycles / 64ms• Power supply: Vdd,Vddq:2.5V±0.1V • Programmable Burst length (2,4,8)• Serial Presence Detect with EEPROM
