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 (N1, N2, <...> Nn) in a neural network, and can provide an adaptive-learning neuron circuit (N1, N2, <...> Nn) for changing an interval of output pulses by learning by connecting a simple pulse generating circuit consisting of at least capacitance, resistance, unijunction transistor UJT and MISFET. A product-sum operation circuit element according to the present invention, comprises an insulator substrate (35), a single crystal semiconductor thin film (36, 37) having a p-n-p or n-p-n structure in a lateral direction formed in the shape of stripes on the insulator substrate (35), a ferroelectric thin film (38) deposited thereon for covering at least the semiconductor stripe structure (36, 37), and a stripe-like gate electrode 39 consisting of a metal or a polycrystalline semiconductor formed thereon for intersecting said semiconductor stripes at a right angle or suitable angle. <IMAGE> |
