Patent ID: 7838873

Claim:
A stochastically based integrated circuit encryption structure, comprising: a substrate having an array of individual cells formed thereupon, each of the array cells including at least one layer therein formed in a manner so as to result in a nanopore structure of varying shape and size distribution among the 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, wherein the array further comprises: a lower conductive layer common to each of the array cells; a short prevention layer, common to each of the array cells, the short prevention layer formed over the lower conductive layer; an intermediate layer formed over the short prevention layer and patterned according to the nanopore structure of varying shape and size distribution, the intermediate layer comprising one of a dielectric layer and a resistive material layer; and an upper conductive layer formed over the intermediate layer.
