HIGH -SPEED 2K ×16的CMOS双口静态RAM HIGH-SPEED 2K x 16 CMOS DUAL-PORT STATIC RAMS
Description
The IDT7133/7143 are high-speed 2K x 16 Dual-Port Static RAMs. The IDT7133 is designed to be used as a stand-alone 16-bit Dual-Port RAM or as a “MASTER” Dual-Port RAM together with the IDT7143 “SLAVE” Dual-Port in 32-bit-or-more word width 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.
