Product Summary
The IDT7132LA55CB is a high-speed 2K x 8 Dual-Port Static RAM. The IDT7132LA55CB is designed to be used as a stand-alone 8-bit Dual-Port RAM or as a “MASTER” Dual-Port RAM together with the IDT7142 “SLAVE” Dual-Port in 16-bit-or-more word width systems. Using the IDT MASTER/SLAVE Dual-Port RAM approach in 16-or-more-bit memory system applications results in full-speed, error-free operation without the need for additional discrete logic.
