Ddr2 800mhz Dimm Memory Module - 1.8v Lead-free, 240-pin Socket Type, Double Data-rate Architecture, Compatible With Computers And Digital Devices

1) DDR2 800MHz to 533MHz
2) 240-pin socket type dual in line memory module (DIMM)
3) Lead-free 1.8V power supply
4) Data rate: 800Mhz/667Mbps/533Mbps
5) 1.8V (SSTL-18 compatible) I/O
6) Double-data-rate architecture: two data transfers per clock cycle
7) Bidirectional, differential data strobe (DQS and /DQS) is transmitted/received with data, to be used in capturing data at the receiver
8) DQS is edge aligned with data for reading: center aligned with data for writing
9) Differential clock inputs (CK and /CK)
10) DLL aligns DQ and DQS transitions with CK transitions
11) Commands entered on each positive CK edge: data and data mask referenced to both edges of DQS
