A fuzzy logic circuit for operating a fuzzy logic with 'fuzziness' taken into account has an operation section memory unit in which the result of operation to be outputted in response to an input is stored in an address specified by the input, the result of operation being rewritable, whereby the change in the contents of a fuzzy logic operation to be performed can be handled merely by rewriting the contents of the operation section memory unit.

Programmable fuzzy logic circuits

A coincidence circuit for detecting when n-bit binary input data coincides with the current value of an n-bit counter. A plurality of '1' detecting circuits determine, when a corresponding input bit is one, whether a corresponding counter bit is also one. A first-coincidence detecting circuit determines the first time that all the '1' input bits have corresponding '1' clock bits. Each '1' detecting circuit includes an inverter and a NOR gate. The first-coincidence detecting circuit includes an OR gate and a latch circuit.
