PURPOSE: To freely form a fuzzy logic arithmetic by leading a fuzzy logic arithmetic output signal out of an external terminal of a MAX circuit.
CONSTITUTION: A MIN output signal line LO1 is provided to lead the output voltage y1 - ym of each MIN circuit 21 in a semiconductor chip 10. At the same time, a MAX input signal line LI2 is connected to three input terminals of each MAX circuit 31 forming a MAX circuit array. All lines LO1 are connected to all lines LI2 via the micro-fuses 39. The lines LI2 are connected to a terminal 14 connected to the ground via a resistor R3 at an end part opposite to the input terminal of the circuit 31. In such a constitution, the MIN and MAX serving as the basic logics for a fuzzy logic arithmetic can be optionally combined for execution of operations.
