Service Description
1) DDR 400/333 & DDRII 533/667/800 MHz
2) 168/184/240-pin socket type dual in line memory module (DIMM)
3) 2.6V power supply
4) Data rate: 400/333/533/667/800Mbps (max.)
5) 2.5V (SSTL-2 compatible) I/O for DDR I products,1.8V power supply for DDR II products
6) Double data rate architecture, two data transfers per clock
7) Bi-directional, data strobe (DQS) is transmitted/received with data, to be used
in capturing data at the receiver
8) Data inputs and outputs are synchronized with DQS
9) DQS is edge aligned with data for read, center aligned with data for write
10) Differential clock inputs (CK and CK)
11) DLL aligns DQ and DQS transitions with CK transitions
12) Commands entered on each positive CK edge, data referenced to both
