Abstract :
General theories on multiple-valued static random-access memory (RAM) are investigated. The criteria for a stable and an unstable mode are proved with strict mathematical methods and expressed with diagrammatic representation. A circuit design and realization for NMOS six-transistor ternary and quaternary static RAM cells based on the theories are proposed and simulated with PSPICE. A 10-valued CMOS current-mode static RAM cell is also presented and fabricated with standard 5-μm CMOS technology. Both PSPICE simulations and experiments indicate that the general theories presented are very useful and effective tools in optimal design and circuit realization of multiple-valued static RAMs
