36-Mbit DDR II+ SRAM 2-Word Burst Architecture (2.5 Cycle Read Latency)
36-Mbit DDR II+ SRAM 2-Word Burst Architecture (2.5 Cycle Read Latency)
Features
- 36-Mbit density (4 M × 8, 4 M × 9, 2 M × 18, 1 M × 36)
- 550 MHz clock for high bandwidth
- 2-word burst for reducing address bus frequency
- Double data rate (DDR) interfaces
(data transferred at 1100 MHz) at 550 MHz
- Available in 2.5 clock cycle latency
- Two input clocks (K and K) for precise DDR timing
- SRAM uses rising edges only
- Echo clocks (CQ and CQ) simplify data capture in high speed systems
- Data valid pin (QVLD) to indicate valid data on the output
- Synchronous...
