The design of the memory circuit is based on finding an appropriate many-valued logical operation which replaces the Sheffer resp. Pierce operation which is used in the R-S memory circuit known from the two-valued logical circuits. We prove that, in the ideal case, the generalized many-valued R-S memory circuit can store and hold any logical value from the real interval [0,1] in a similar way as the two valued R-S memory circuit. The proposed many-valued R-S memory circuit allows moreover to design a many-valued level-controlled memory circuit and a many-valued edge-controlled memory circuit. Problems of the stability of the memory circuit with respect to small errors of input signals and to small errors of the gates are discussed. It is shown that unstability of the gates may violate the proper functionality of the circuit. Nevertheless, the problem can be solved by restricting the set of logical values, i.e. the interval [0,1], to a finite discrete subset of this interval. }, keywords = { Memory circuit, flip-flop, multi-valued hardware design, many-valued logical circuit design }, authorship = { 100 }, project = { specific research }, www = { http://www.memics.cz }, }
