Claim One:
1. A fuzzy neuron device assembly comprising: a plurality of fuzzy neuron devices each of said plurality of fuzzy neuron devices including: (a) a plurality of synapses, each of which defines a membership function, receives an input signal, and outputs an output signal specified by application of said input signal to said membership function, (b) a first minimum value computing circuit extracting a first minimum value signal from among output signals output from said plurality of synapses, (c) an extension circuit receiving said first minimum value signal, and (d) an extension terminal connecting said extension circuit to the extension circuit of other ones of said plurality of fuzzy neuron devices; and a second minimum value computing circuit comprising a plurality of said extension circuits connected to each other through said extension terminal of each of said plurality of fuzzy neuron devices, the second minimum value computing circuit extracting a second minimum value signal in said fuzzy neuron device assembly from said first minimum value signals of each of said plurality of fuzzy neuron devices wherein each of said extension circuits computes the second minimum value signal from among said first minimum value signals, said extension circuit includes a transistor having a base, a collector and an emitter, said first minimum value signal is supplied to the base of said transistor, a constant voltage source is connected to the collector of said transistor, and the emitter of said transistor is connected to said extension terminal, a constant current source and an output circuit, the output circuit receiving and outputting the second minimum value signal.
