OCTOBER 2008 DSC-3490/7 IDT70914S High-Speed 36K 4K x 9 Synchronous Dual-Port Static RAM The IDT70914 is a high-speed 4K x 9 bit synchronous Dual-Port RAM. The memory array is based on Dual-Port memory cells to allow simultaneous access from both ports. Registers on control, data, and address inputs provide low set-up and hold times. The timing latitude provided by this approach allow systems to be designed with very short cycle times. With an input data register, this device has been optimized for applications having unidirectional data flow or bi-directional data flow in bursts. The IDT70914 utilizes a 9-bit wide data path to allow for parity at the user's option. This feature is especially useful in data communication applications where it is necessary to use a parity bit for transmission/ Military, Industrial and Commercial Temperature Ranges reception error checking. Fabricated using IDT’s CMOS high-performance technology, these Dual-Ports typically operate on only 850mW of power at maximum highspeed clock-to-data output times as fast as 12ns. An automatic power down feature, controlled by CE, permits the on-chip circuitry of each port to enter a very low standby power mode.
