ABSTRACT:
A semiconductor device of simple circuit capable of comparing the magnitudes of plural data at a high speed. This device has an inverter circuits formed by neuron MOS transistors; means for applying to a first input gate of the inverter circuit a first signal voltage which is common to the inverters belong to the foregoing inverter circuit group; means for applying predetermined second signal voltage to one or more second inout gates other than the first input gate of the inverter; and means for detecting the variation of the output voltage in at least one inverter circuit of the inverter circuit group due to the variation with time of either the first or the second signal voltage or both, and for applying positive feedback to given inverters of the inverter circuit group according to the detection.
