Abstract
A method of forming a one-time-programmable resistive random access memory bit includes forming a resistive switching layer on a bottom electrode layer. The method also includes forming a top electrode layer on the resistive switching layer. The method also includes applying a forming voltage to the resistive switching layer, such that the electric potential of the top electrode layer is lower than that of the bottom electrode layer. The method also includes performing a bake process on the resistive switching layer. The vacancies in the resistive switching layer are randomly distributed.
