Description
The IDT70V28 is designed to be used as a stand-alone 1024K-bit
Dual-Port RAM or as a combination MASTER/SLAVE Dual-Port RAM
for 32-bit-or-more word system. Using the IDT MASTER/SLAVE Dual-
Port RAM approach in 32-bit or wider memory system applications
results in full-speed, error-free operation without the need for addi-
tional discrete logic.
address, and I/O pins that permit independent, asynchronous access
