Abstract
A neural network, and a method of storing information and retrieving it by such network. The network comprises neurons, synapses and switches, and when required also rectifying means. The network is based on a substance which undergoes a reversible change from stable state A to stable state B, and this substance can also be changed from state A to another state C, which change is also reversible, where each change provides a measurable electrical pulse. The change of state is brought about by means of illumination for a predetermined period of time at a certain wavelength, it being possible to convert a desired part of the substance from one state to the other.
