Fuzzy logic computers and circuits

A fuzzy computer comprising:

• a fuzzy memory for successively outputting a plurality of fuzzy membership electric signals, each said fuzzy membership electric signal being distributed on a plurality of lines in accordance with a predetermined sequence;
• a fuzzy inference engine which receives as inputs a plurality of outputs from said fuzzy memory for successively executing predetermined fuzzy operations and successively outputting the results of said operations;
• and
• an output circuit for executing a predetermined connective operation with regard to the result of each fuzzy operation successively outputted by said fuzzy inference engine.

A fuzzy membership function generator comprising:

• an electric signal distribution generator circuit for generating an electric signal, which is distributed on a plurality of lines, representing a basic fuzzy membership function having a predetermined shape;
• a plurality of output terminals respectively corresponding to said plurality of lines of said distribution generator circuit;
• and
• a pass array comprising a switch group and a line group for connecting lines of said electric signal distribution generator circuit to said output terminals at respective positions corresponding to said lines or at respective positions shifted a predetermined number of lines from said lines of said distribution generator circuit.

A MIN/MAX circuit comprising:

• a first comparator for performing a MIN operation and which includes a first plurality of three-terminal control elements having control terminals to which inputs are respectively applied and carrier injection terminals connected in common to form an output terminal, said first plurality of three-terminal control elements being connected in such a manner that a three-terminal control element of said first plurality of three-terminal control elements which has the smallest input applied thereto is rendered conductive;
• and
• a second comparator for performing a MAX operation and which includes a second plurality of three-terminal control elements having control terminals to which inputs are respectively applied and carrier injection terminals connected in common to form output terminals, said second plurality of three-terminal control elements being connected in such a manner that a three-terminal control element of said second plurality of three-terminal control elements which has the largest input applied thereto is rendered conductive;
• said first and second comparators being connected in cascade.
