Features
- - VDD=VDDQ=2.5V+0.2V - Double data rate architecture; two data transfers per clock cycle - Bidirectional, data strobe (DQS) is transmitted/received with data - Differential clock inputs (CLK and /CLK) - DLL aligns DQ and DQS transitions - Commands are entered on each positive CLK edge - Data and data mask are referenced to both edges of DQS - 4-bank operations are controlled by BA0, BA1 (Bank Address) - /CAS latency- 2.0/2.5 (programmable) - Burst length- 2/4/8 (programmable) - Burst type- seque.
