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 |
