ABSTRACT:
The present invention relates to a semiconductor integrated circuit. In greater detail, the present invention relates to a semiconductor integrated circuit which conducts calculations using a voltage adding function by means of capacity and threshold operations. The semiconductor integrated circuit in accordance with the present invention is characterized in that, in a circuit wherein the output of a first inverter circuit and the input of a second inverter circuit are connected at a first contact point, the output of the second inverter and the input of the first inverter are connected at a second contact point, and a means is provided for generating a difference in potential between the first contact point and the second contact point, an electrically floating electrode and a plurality of input electrodes, which are provided via capacity elements with this electrode, are provided, and a means is provided for in effect determining the difference in potential by means of the potentials applied to the input electrodes.
