IDT7024数据手册Renesas中文资料规格书

描述 Description

The IDT7024 is a high-speed 4Kx 16 Dual-Port Static RAM. The IDT7024 is designed to be used as a stand-alone 64K-bit Dual-Port RAM or as a combination MASTER/SLAVE Dual-Port RAM for 32-bit or more word systems. 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 additional discrete logic.
