FEATURES



533MHz DDR operation (1.067 Gb/s/pin data rate)



38.4Gb/s peak bandwidth (x18 at 533 MHz clock

frequency)



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
