General Description

The IDT71321/IDT71421 are high-speed 2K x 8 Dual-Port Static RAMs with internal interrupt logic for interprocessor communications.

The IDT71321 is designed to be used as a stand-alone 8-bit DualPort Static RAM or as a "MASTER" Dual-Port Static RAM together with the IDT71421 "SLAVE" Dual-Port in 16-bit-or-more word width systems.

Using the IDT MASTER/SLAVE Dual-Port Static RAM approach in 16-or-more-bit memory system applications results in full speed, er
