Abstract
A method for physically unclonable function (PUF) cell-pair remapping includes combining PUF cell-pairs between PUF cells in a first array and PUF cells in a second array, acquiring physical parameters for each of the PUF cell-pairs, selecting PUF cell-pairs based on a comparison of the acquired parameters with a first reference, and remapping the selected PUF cell-pairs.
