This document describes the features and characteristics of IDT7134SA/LA high-speed 4K x 8 dual-port static RAM, including high-speed access, low-power operation, asynchronous operation, battery backup operation, and TTL compatibility.
The IDT7134 is a high-speed 4K x 8 Dual-Port Static RAM designed for systems where on-chip hardware port arbitration is not required. It provides two independent ports with separate control, address, and I/O pins that permit independent, asynchronous access for reads or writes to any location in memory.
The device is available in both Standard (SA) and Low-power (LA) versions. The LA version offers battery backup data retention capability, allowing the chip to retain data from a 2V battery when main power is removed. It is fabricated using CMOS high-performance technology and is offered in various hermetic and plastic packages.
