Structure and method for stochastic integrated circuit personalization

A method of forming a stochastically based integrated circuit encryption structure, the method comprising:

• forming a lower conductive layer over a substrate;
• forming a short prevention layer over the lower conductive layer;
• forming an intermediate layer over the short prevention layer, the intermediate layer comprising one of a dielectric layer and a resistive material layer, wherein the intermediate layer is characterized by randomly structured nanopore features;
• forming an upper conductive layer over the random nanopore structured intermediate layer;
• and
• patterning the upper conductive layer into an array of individual cells, wherein a measurable electrical parameter of the individual cells has a random distribution from cell to cell with respect to a reference value of the electrical parameter.
