•

Burst type (BT):



Sequential (4, 8)



Precharge: auto precharge option for each burst

access

•

•

Refresh: auto-refresh, self-refresh

Features

•

Double-data-rate architecture; two data transfers per

clock cycle

•

The high-speed data transfer is realized by the 4 bits

prefetch pipelined architecture

•

Bi-directional differential data strobe (DQS and /DQS)

is transmitted/received with data for 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

•

Data mask (DM) for write data

•

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

•

Programmable RDQS, /RDQS output for making

organization compatible to

4 organization

•

/DQS, (/RDQS) can be disabled for single-ended

Data Strobe operation

•

Refresh cycles: 8192 cycles/64ms



Average refresh period

7.8µs at 0°C

≤

≤ +85°C

3.9µs at

+85°C <

≤ +95°C

•
