Features

JEDEC Standard

Internal pipelined double-data-rate architecture, two data

access per clock cycle

Bi-directional data strobe (DQS)

No DLL; CLK to DQS is not synchronized.

Differential clock inputs (CLK and CLK )

Quad bank operation

CAS Latency : 2, 3

Burst Type : Sequential and Interleave

Burst Length : 2, 4, 8

Special function support

-

PASR (Partial Array Self Refresh)

-

Internal TCSR (Temperature Compensated Self

Refresh)

-

DS (Driver Strength)

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 READ; center-aligned

with data for WRITE

Data mask (DM) for write masking only

VDD/VDDQ = 1.7V ~ 1.9V

Auto & Self refresh

15.6us refresh interval (64ms refresh period, 4K cycle)

1.8V LVCMOS-compatible inputs

60 ball BGA package
