Abstract
A semiconductor device capable of executing size comparison operations on a plurality of data at high speed and in real time and using simple circuitry. An inverter circuit group is used containing a plurality of inverter circuits constructed using neuron MOS transistors. Predetermined signal voltages are applied from the exterior to the first input gates of the inverter circuits, and the output signals of all inverters contained in the inverter circuit group are inputted into a first logical arithmetic circuit and a second logical arithmetic circuit, and the output signal of the first logical arithmetic circuit is inputted into a third logical arithmetic circuit controlled by the output signal of the second logical arithmetic circuit, and the output of the third logical arithmetic circuit is fed back to the second input gates of the inverter circuits contained in the inverter circuit group. Bye use of the output signals of the inverter circuit groups, the position having the maximum voltage among the signal voltages inputted into the inverter circuit groups is specified.
