Abstract
Abstract Neural network type information processing devices have been proposed. In these devices, a matrix structure is utilized with impedance at the matrix intersection points. It has been found that excellent versatility in design is achieved by utilizing photoconductors at these intersection points and thus affording the possibility of controlling impedance by, in turn, controlling the level of incident light.
