Recent research in fuzzy logic indicates a growing interest in practical and commercial applications. An improved fuzzy processor would embody both fuzzy (multilevel) and classical (binary) information processing in the same machine. One of the basic building blocks for the fuzzy processor is the fuzzy memory element. Such a circuit is proposed in the Letter.
