CY7C1241V18 - 36-Mbit QDR-II SRAM 4-Word Burst Architecture

Description

The CY7C1241V18, CY7C1256V18, CY7C1243V18, and CY7C1245V18 are 1.8V Synchronous Pipelined SRAMs, equipped with Quad Data Rate-II+ (QDR-II+) architecture.

QDR-II+ architecture consists of two separate ports to access the memory array.

Features

  • Separate independent read and write data ports.
  • Supports concurrent transactions.
  • 300 MHz to 375 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 750 MHz) at 375 MHz.
  • Read latency of 2.0 clock cycles.
  • Two input clocks (K and K) for precise DDR timing.
  • SRAM uses rising edges only.
  • Echo clocks (CQ and CQ).
