70T651-9S Overview
The IDT70T651/9 is a high-speed 256/128K x 36 Asynchronous Dual-Port Static RAM. The IDT70T651/9 is designed to be used as a stand-alone 9216/4608K-bit Dual-Port RAM or as a bination MASTER/SLAVE Dual-Port RAM for 72-bit-or-more word system. Using the IDT MASTER/SLAVE Dual-Port RAM approach in 72-bit or wider memory system applications results in full-speed, error-free operation without the need for additional...
