DESCRIPTION:

The IDT7005 is a high-speed 8K x 8 Dual-Port Static RAM. The IDT7005 is designed to be used as a stand-alone Dual Port RAM or as a combination MASTER/SLAVE Dual-Port RAM for 16-bit-or-more word systems. Using the IDT MASTER/SLAVE Dual-Port RAM approach in 16-bit or wider memory system applications results in full-speed, error-free operation without the need for additional discrete logic.

FEATURES:

? True Dual-Ported memory cells which allow simultaneous access of the same memory location

? High-speed access

— Military: 20/25/35/55/70ns (max.)

— Commercial:15/17/20/25/35/55ns (max.)

? Low-power operation

— IDT7005S

Active: 750mW (typ.)

Standby: 5mW (typ.)

— IDT7005L

Active: 750mW (typ.)

Standby: 1mW (typ.)

? IDT7005 easily expands data bus width to 16 bits or more using the Master/Slave select when cascading

more than one device

?M/S= H for BUSYoutput flag on Master, M/S= L for BUSYinput on Slave

? Busy and Interrupt Flags

? On-chip port arbitration logic

? Full on-chip hardware support of Semaphore signaling between ports
