Description
The IDT70V659/58/57 is a high-speed 128/64/32K x 36 Asynchronous Dual-Port Static RAM. The IDT70V659/58/57 is designed to be used as a stand-alone 4/2/1Mbit Dual-Port RAM or as a combination MASTER/ SLAVE Dual-Port RAM for 72-bit-or-more word system. Using the IDT MASTERSLAVE Dual-Port RAM approach in 72-bit or wider memory system applications results in full-speed, error- free operation without the need for additional discrete logic.
Features
◆ True Dual-Port memory cells which allow simultaneous access of the same memory location
◆ High-speed access
– Commercial: 10/12/15ns (max.)
– Industrial: 12/15ns (max.)
◆ Dual chip enables allow for depth expansion without external logic
◆ IDT70V659/58/57 easily expands data bus width to 72 bits or more using the Master/Slave select when cascading more than one device
◆ M/S = VIH for BUSY output flag on Master, M/S = VIL for BUSY input on Slave
◆ Busy and Interrupt Flags
◆ On-chip port arbitration logic
◆ Full on-chip hardware support of semaphore signaling between ports
◆ Fully asynchronous operation from either port
