Features
- Double-data-rate architecture; two data transfers per clock cycle
- The high-speed data transfer is realized by the 8 bits prefetch pipe- lined architecture
- Bi-directional differential data strobe (DQS and DQS) is transmitted/ received with data for capturing data at the receiver
- DQS is edge-aligned with data for READs; center-aligned with data for WRITEs
- Differential clock inputs (CK and CK)
- DLL aligns DQ and DQS transitions with CK transitions
- mands entered on each positive CK edge; data and data mask referenced to both edges of DQS
- Data mask (DM) for write data
- Posted CAS by programmable additive latency for better mand and data bus efficiency
- On-Die Termination (ODT) for better signal quality
- Synchronous ODT
- Dynamic ODT
- Asynchronous ODT
- Multi Purpose Register (MPR) for pre-defined pattern read out
- ZQ calibration for DQ drive and ODT
- RESET pin for Power-up sequence and reset function
- SRT range : Normal/extended
- Programmable Output driver...
