Features
-
533MHz DDR operation (1.067 Gb/s/pin data rate)
38.4Gb/s peak bandwidth (x36 at 533 MHz clock
frequency)
-
Differential input clocks (CK, CK#)
-
Differential input data clocks (DKx, DKx#)
-
On-die DLL generates CK edge-aligned data and
-
Reduced cycle time (15ns at 533MHz)
-
32ms refresh (16K refresh for each bank; 128K
refresh command must be issued in total each 32ms)
8 internal banks
-
Non-multiplexed addresses (address multiplexing
option available)
-
SRAM-type interface
-
Programmable READ latency (RL), row cycle time,
and burst sequence length
-
Balanced READ and WRITE latencies in order to
optimize data bus utilization
-
Data mask signals (DM) to mask signal of WRITE
data; DM is sampled on both edges of DK.
