ABSTRACT:
A semiconductor neural network constructed in accordance with models of vital nerve cells has photosensitive elements as coupling elements providing degrees of coupling between neurons which are modeled vital nerve cells. The conductance values of the photosensitive elements can be set by light. Due to such structure, not only the degrees of coupling of all the coupling elements can be simultaneously programmed but signal lines for programming the degrees of coupling can be eliminated in the network, whereby a semiconductor neural network having a high degree of integration can be implemented without additional complicating fabrication steps.
