Concept of Level-Controlled R-S Fuzzy Memory Circuit

In this paper we present a level-controlled fuzzy memory element based on a generalization of the classical two-valued R-S flip-flop. Our memory element is small, simple and hazardless and thus suitable for a hardware implementation. We show that the circuit is stable with respect to small errors of input signals as well as to small errors of the gates; we show that this stability is conditioned by restricting the set of fuzzy values to a finite subset of the interval [0, 1].
