DESCRIPTION:

The IDT70V07 is a high-speed 32K x 8 Dual-Port Static

RAM. The IDT70V07 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.
