Abstract

PURPOSE:To ensure the writing and reading for an optional information by securing a correspondence to the binary signals before and after the change of the characteristics through utilization of the fact that the forward and backward characteristics of the junction change in a non-reversible way according to the state of the reverse bias given by the junction.
