KEY FEATURES

• Double Data Rate architecture: two data transfers per clock cycle

• High-speed data transfer is realized by 8 bits prefetch pipelined architecture

• Bi-directional differential data strobe (DOS and /DQS) is transmitted/received

with data for capturing data at the receiver

• DOS is edge-aligned with data for READS; center-aligned with data for WRITES

• Differential clock inputs (CK and /CK)

• DLL aligns DQ and DOS 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 (ODD for better signal quality)

— Synchronous ODT

— Dynamic CDT

— Asynchronous ODT

• Multi-Purpose Register (MPR) for pre-defined pattern read out

• ZQ calibration for DO 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
