1GB A-Data DDR SO-DIMM PC2100 266MHz (CL2.5) 200 pins by Adata

The A-DATA DDR266 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 DDR266 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.

With 64Mx8 chips (16 chips per module) which makes this module very compatible across a range of notebook computers.
