36-Mbit QDR® II SRAM Two-Word Burst Architecture

特性

  • 分立的独立读和写数据端口
    • 支持并发事务处理
  • 333 MHz 时钟实现高带宽
  • Two-word burst on all accesses
  • 读和写端口均为双倍数据速率 (DDR) 接口(数据传输速率 666 MHz),工作频率 333 MHz
  • 两个输入时钟(K 和 K)用于精确 DDR 定时
    • SRAM 仅使用上升沿
  • 两个输入时钟用于输出数据(C 和 C),以将时钟偏移和飞行时间的不匹配降至最低
  • 回波时钟(CQ 和 CQ)简化高速系统中的数据采集

功能描述

The CY7C1425KV18, CY7C1412KV18, and CY7C1414KV18 are 1.8 V synchronous pipelined SRAMs, equipped with QDR II architecture. QDR II 架构包含两个分立的端口:即用于访问内存阵列的读端口和写端口。读端口有专用的数据输出来支持读操作,写端口则有专用的数据输入来支持写操作。QDR II architecture has separate data inputs and  data outputs to completely eliminate the need to “turnaround” the data bus that exists with common I/O devices.

Dear valued customer,

Thank you for choosing our products. They come with all the know-how and passion that our engineers have put into it. As you probably already know, Cypress is now Infineon. This is a major step for our company, but also for the good of you.
