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 glassűepoxy 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: VddVddq:2.5V¦0.1V Programmable Burst length (248) Serial Presence Detect with EEPROM
