The 71421 is a high-speed 2K x 8 Dual-Port Static RAM with internal interrupt logic for interprocessor communications. It is designed to be used as a “ SLAVE ” Dual-Port RAM together with the 71321 “ MASTER ” Dual-Port in 16-bit-or-more word width systems which would result in full-speed, error free operation without the need for additional discrete logic. An automatic power down feature, controlled by CE , permits the on chip circuitry of each port to enter a very low standby power mode.
