... IDT70V05S/L High-Speed 3. Dual-Port Static RAM Description The IDT70V05 is a high-speed Dual-Port Static RAM. The IDT70V05 is designed to be used as a stand-alone 64K-bit Dual-Port SRAM combination MASTER/SLAVE Dual-Port SRAM for 16-bit- or-more word systems. Using the IDT MASTER/SLAVE Dual-Port SRAM approach in 16-bit or wider memory system applications results in full- speed, error-free operation without the need for additional discrete logic ...
