Features
- Double-data-rate architecture; two data transfers per clock cycle.
- Bidirectional data strobe DQS.
- Four banks operation.
- Differential clock inputs(CK and CK).
- DLL aligns DQ and DQS transition with CK transition.
- MRS cycle with address key programs -. Read latency 2, 2.5 (clock) -. Burst length (2, 4, 8) -. Burst type (sequential & interleave).
- All inputs except data & DM are sampled at the positive going edge of the system clock(CK).
