Abstract
A switching element is disclosed which comprises an element comprising two electrodes and an organic insulative region interposed between said two electrodes. The element has a memory property and is capable of being switched between different resistance states upon the application of a predetermined voltage. The switching element also comprises a photosensitive region which has an electrical property which is changed by irradiation of light. The photosensitive region is arranged to change a magnitude of voltage applied to the element. The switching device also comprises a means for applying a biasing voltage to the element and the photosensitive region. This biasing voltage is of such a magnitude as to initiate one of the resistance states in said element, having the memory property when light is irradiated on the photosensitive region.
