Fuzzy Flip-flop

  • Chapter
Fuzzy Logic

Abstract

A great deal of research had been directed towards the realization of a ‘fuzzy computer’. A few types of fuzzy processors which can perform various fuzzy operations, e.g. fuzzy negation, min, max and fuzzy inference, have been proposed and realized by Yamakawa [1, 2] and Togai [3]. These fuzzy inference chips have opened new opportunities for artificial intelligence. However, all of them were based on single-step fuzzy inference. In oder to realize multi-stage fuzzy inference, fuzzy memory modules are indispensable. In the case of an ‘ordinary’ computer, a binary flip-flop circuit, which can memorize single bits of information has been widely used as a fundamental element of memory modules.
