Features
Double-data-rate architecture; two data transfers per
clock cycle
The high-speed data transfer is realized by the 2 bits
prefetch pipelined architecture
Bi-directional data strobe (DQS) is transmitted
/received with data for capturing data at the receiver
Data inputs, outputs, and DM are synchronized with
DQS
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
Commands entered on each positive CK edge; data
and data mask referenced to both edges of DQS
Data mask (DM) for write data
