72-Mbit QDR® II+ SRAM Four-Word Burst Architecture with RadStop™ Technology

특징

  • Separate independent read and write data ports
    • Supports concurrent transactions
  • 250 MHz clock for high bandwidth
  • Four-word burst for reducing address bus frequency
  • Double data rate (DDR) interfaces on both read and write ports at 250 MHz (data transferred at 500 MHz)
  • 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 read and write ports
  • Separate port selects for depth expansion
