IDT7025S/L is a high-speed dual-port static RAM chip produced by Integrated Device Technology, Inc. It has true dual-port memory cells that allow simultaneous access to the same memory location. It has low power consumption of up to 750 mW and a high access speed of 20/25/35/55/70 ns.
The document describes the IDT7025 as a high-speed 8K x 16 Dual-Port Static RAM designed for use as a stand-alone 128K-bit memory or as a Master/Slave component in 32-bit systems. It features true dual-porting allowing simultaneous access to the same memory location and includes separate upper-byte and lower-byte control for multiplexed bus compatibility.
The datasheet provides detailed information on pin configurations, truth tables for read/write and semaphore control, absolute maximum ratings, and DC electrical characteristics. It covers both standard (S) and low-power (L) versions, specifying performance metrics such as access times ranging from 15ns to 70ns depending on the grade.
