Key Features
- Double Data Rate architecture: two data transfers per clock cycle
- Bi-directional, differential data strobes (DQS and /DQS) are transmitted/received with data
- Edge-aligned with Read data and center-aligned with Write data
- DLL aligns DQ and DQS transitions with clock
- Differential clock inputs (CLK and /CLK)
- Data masks (DM) for write data
- Commands entered on each positive CLK edge, data and data mask are referenced to both edges of /DQS
- Posted /CAS programmable additive latency supported to make command and data bus efficiency
- Read Latency = Additive Latency plus CAS Latency (RL = AL + CL)
- Off-Chip-Driver impedance adjustment (OCD) and On-Die-Termination (ODT) for better signal quality
- Auto-precharge operation for read and write bursts
- Auto Refresh and Self Refresh modes
- Precharged Power Down and Active Power Down
- Write Data Mask
- Write Latency = Read Latency - 1 (WL = RL - 1)
