Detail Description:

1) 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: 533/667/800Mbps (max.)

5) 2.5 V (SSTL-2 compatible) I/O for DDR I products,1.8Vpower supply for DDR II products

6) Double-data-rate architecture, two data transfers per clock cycle

7) Bi-directional, differential 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 and data mask referenced to both edges of DQS

13) Four internal banks for concurrent operation (component)

14) Data mask(DM) for write data

15) Auto precharge option for each burst access

16) Programmable burst length: 2, 4, 8

17) Programmable/CAS latency (CL): 3

18) Programmable output driver strength: normal/weak

19) Refresh cycles: (8192 refresh cycles/64ms)

20) 7.8US maximum average periodic refresh interval

21) Posted CAS by programmable additive latency for better command and data bus efficiency

22) Off-chip-driver impedance adjustment and on-die-termination for better signal quality

23) DQS can be disabled for single-ended data strobe operation

24) 2 variations of refresh

25) Auto refresh

26) Self refresh
