1Overview
1.1
Features
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 referenced to both edges of DQS
Burst Lengths: 2, 4, or 8
CAS Latency: 1.5 (DDR200 only), 2, 2.5, 3
Auto Precharge option for each burst access
Auto Refresh and Self Refresh Modes
RAS-lockout supported
