描述 Description

The IDT7016 is a high-speed 16K x 9 Dual-Port Static RAM. The IDT7016 is designed to be used as stand-alone Dual-Port RAMs or as a combination MASTER/SLAVE Dual-Port RAM for 18-bit-ormore wider systems. Using the IDT MASTER/SLAVE Dual-Port RAM approach in 18-bit or wider memory system applications results in full-speed, error-free operation without the need for additional discrete logic.
