Double data rate architecture: two data transfers per clock cycle Bidirectional data strobe (DQS) is transmitted and received with data, to be used in capturing data at the receiver DQS is edge-aligned with data for reads and is center-aligned with data for writes Differential clock inputs (CK and CK) Four internal banks for concurrent operation Data mask (DM) for write data DLL aligns DQ and DQS transitions with CK transitions Commands entered on each positive CK edge; data and data mask re.
