The 70V639 is a high-speed 128K x 18 Asynchronous Dual-Port Static RAM designed to be used as a stand-alone Dual-Port RAM or as a combination MASTER / SLAVE Dual-Port RAM for 36-bit-or-more word system. Using the IDT MASTER / SLAVE Dual-Port RAM approach in 36-bit or wider memory system applications results in full-speed, error-free operation without the need for additional discrete logic. An automatic power down feature controlled by the chip enables (either CE0 or CE1 ) permit the on-chip circuitry of each port to enter a very low standby power mode.
