36-Mbit QDR™-II+ SRAM 4-Word Burst Architecture (2.5 Cycle Read Latency)
Features
- Separate independent read and write data ports
- Supports concurrent transactions
- 300 MHz to 400 MHz clock for high bandwidth
- 4-Word Burst for reducing address bus frequency
- Double Data Rate (DDR) interfaces on both read and write ports
(data transferred at 800 MHz) at 400 MHz
- Read latency of 2.5 clock cycles
- 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
- Single multiplexed address input bus latches address inputs for both read and write ports
- Separate Port Selects for depth expansion
- Data valid pin (QVLD) to indicate valid data on the output
- Synchronous internally self-timed writes
- Available in x8, x9, x18, and x36 configurations
- Full data coherency providing most current data
- Core VDD =...
