Abstract
A plurality of physically unclonable function (PUF) bit cells are surveyed by supplying a plurality of threshold control values to the PUF bit cells. Survey results associated with each of the threshold control values are evaluated to determine a threshold control pair having a positive threshold control value and a negative threshold control value among the plurality of threshold control values that results in a desired number PUF bit cells that are strong ones and that are strong zeros.
