Description
Dual-Port Static RAM. The IDT70T633/1 is designed to be used as a
stand-alone 9216/4608K-bit Dual-Port RAM or as a combination MAS-
TER/SLAVE Dual-Port RAM for 36-bit-or-more word system. Using the
IDT MASTER/SLAVE Dual-Port RAM approach in 36-bit or wider
memory system applications results in full-speed, error-free operation
without the need for additional discrete logic.
