PRELIMINARY DATA SHEET
4 banks
Features
DLL is not implemented
Low power consumption
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
Low Power Function below is not supported
TA = 25 C to +85 C
Partal Array Self-Refresh (PASR)
Auto Temperature Compensated Self-Refresh
Deep power-down mode
