Double-data-rate architecture; two data transfers per clock cycle
The high-speed data transfer is realized by the 8 bits prefetch pipelined 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; centeraligned with data for WRITEs
Differential clock inputs (CK and /CK)
DLL aligns DQ and DQS transitions with CK transitions
Commands 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 command and data bus efficiency
On-Die-Termination (ODT) for better signal quality
– Synchronous ODT
– Dynamic ODT
– Asynchronous ODT
Multi Purpose Register (MPR) for temperature read out
ZQ calibration for DQ drive and ODT
Programmable Partial Array Self-Refresh (PASR)
/RESET pin for Power-up sequence and reset function
SRT range:
– Normal/extended
Programmable Output driver impedance control
