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

特性

  • 分立的独立读和写数据端口
    • 支持并发事务处理
  • 250 MHz 时钟实现高带宽
  • 4 字突发降低地址总线频率
  • Double data rate (DDR) interfaces on both read and write ports at 250 MHz (data transferred at 500 MHz)
  • 两个输入时钟(K 和 K)用于精确 DDR 定时
    • SRAM 仅使用上升沿
  • 回波时钟(CQ 和 CQ)简化高速系统中的数据采集
  • 单个复用地址输入总线,能够为读端口和写端口锁存地址输入
  • 单独的端口选择,能够实现深度扩展 (Depth Expansion)
