Description
IDT7008 is designed to be used as a stand-alone 512K-bit 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.
address, and I/O pins that permit independent, asynchronous access for
