IDT70T631S : 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. The IDT70T651/9 has a RapidWrite Mode which allows the designer to perform back-to-back write operations without pulsing the R/W input each cycle. This is especially significant at the 8 and 10ns cycle times of the IDT70T651/9, easing design considerations at these high performance levels. The 70T633/1 can support an operating voltage of either 3.3V or 2.5V on one or both ports, controlled by the OPT pins. The power supply for the core of the device (VDD) remains at 2.5V. 2 IDT70T633/1S High-Speed 2.5V 512/256K x 18 Asynchronous Dual-Port Static RAM .
