70T3799M - DUAL-PORT STATIC RAM

This page provides the datasheet information for the 70T3799M, a member of the 70T3719 DUAL-PORT STATIC RAM family.

Datasheet Summary

Description

The IDT70T3719/99M is a high-speed 256K/128K x 72 bit synchronous Dual-Port RAM.

The memory array utilizes Dual-Port memory cells to allow simultaneous access of any address from both ports.

Registers on control, data, and address inputs provide minimal setup and hold times.

Features

  • True Dual-Port memory cells which allow simultaneous access of the same memory location.
  • High-speed data access.
  • Commercial: 3.6ns (166MHz) 4.2ns (133MHz)(max. ).
  • Industrial: 4.2ns (133MHz) (max. ).
  • Selectable Pipelined or Flow-Through output mode.
  • Counter enable and repeat features.
  • Dual chip enables allow for depth expansion without additional logic.
  • Interrupt and Collision Detection Flags.
  • Full synchronous operation on both ports.
