Features
Power supply: VDD, VDDQ
=
1.8V
±
0.1V
Double-data-rate architecture: two data transfers per
clock cycle
Bi-directional, differential data strobe (DQS and
/DQS) is transmitted/received with data, to be used in
capturing data at the receiver
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
Four internal banks for concurrent operation
Data mask (DM) for write data
Burst lengths: 4, 8
/CAS Latency (CL): 3, 4, 5
Auto precharge operation for each burst access
Auto refresh and self refresh modes
7.8
μ
s average periodic refresh interval
SSTL_18 compatible I/O
Posted CAS by programmable additive latency for
better command and data bus efficiency
Off-Chip-Driver Impedance Adjustment and On-Die-
Termination for better signal quality
