Features
DLL is not implemented
Low power consumption
Partial Array Self-Refresh (PASR)
Auto Temperature Compensated Self-Refresh
(ATCSR) by built-in temperature sensor
Deep power-down mode
Double-data-rate architecture; two data transfers per
one clock cycle
The high-speed data transfer is realized by the 2 bits
prefetch pipelined architecture
Bi-directional data strobe (DQS) is transmitted
/received with data for capturing data at the receiver.
Data inputs, outputs, and DM are synchronized with
DQS
DQS is edge-aligned with data for READs; center-
aligned with data for WRITEs
Differential clock inputs (CK and /CK)
Commands entered on each positive CK edge: data
and data mask referenced to both edges of DQS
Data mask (DM) for write data
Burst termination by burst stop command and
precharge command
Wide temperature range
TA = 25 C to +85 C
