Features
JEDEC Standard
Internal pipelined double-data-rate architecture, two data access per clock cycle
Bi-directional data strobe (DQS)
On-chip DLL
Differential clock inputs (CLK and CLK )
DLL aligns DQ and DQS transition with CLK transition
Quad bank operation
CAS Latency : 2; 2.5; 3
Burst Type : Sequential and Interleave
Burst Length : 2, 4, 8
All inputs except data & DM are sampled at the rising edge of the system clock(CLK)
Data I/O transitions on both edges of data strobe (DQS)
DQS is edge-aligned with data for reads; center-aligned with data for WRITE
Data mask (DM) for write masking only
