Evaluating Ternary Adders using a hybrid Memristor / CMOS approach

Abstract

This paper investigates the potentials of using a hybrid memristor CMOS technology, called MeMOS, for the realisation of ternary adders. Ternary adders exploit the qualitative advantage of multi-value storage capability of memristors compared to conventional CMOS flip-flops storing only binary values in one cell. Furthermore they carry out an addition in O(1) and are therefore considered. The MeMOS approach is compared to a CMOS solution for the ternary adders using multi value memristors as registers concerning the achievable latency and the energy consumption. It is shown that using the TEAM, VTEAM model and a model considering commercially available memristors from Known the approach of using CMOS ternary adders using memristors as multi-value register memory is to prefer. MeMOS circuits have advantages for a static operation mode, i.e. if they are operated after a reset.
