Abstract
The present invention relates to a product-sum operation circuit element and a circuit for addition by weighting a number of signals input in one neuron circuit in a neural network, and can provide an adaptive-learning neuron circuit for changing an interval of output pulses by learning by connecting a simple pulse generating circuit consisting of capacitance, resistance, unijunction transistor and the like. A product-sum operation circuit element according to the present invention, includes an insulator substrate, a single crystal semiconductor thin film having a p-n-p or n-p-n structure in a lateral direction formed in the shape of stripes on the insulator substrate, a ferroelectric thin film deposited thereon for covering at least the semiconductor stripe structure, and a stripe-like electrode consisting of a metal or a polycrystalline semiconductor further formed thereon for intersecting the semiconductor stripes at a right angle or suitable angle.
