Abstract
A method of generating a physical unclonable function (PUF) key uses a value read from an array of bitcells in rows defined by pairs of true and complement wordlines and columns defined by pairs of true and complement bitlines, each bitcell having a pull-up network coupled to a complement wordline and to the true and complement bitlines, and having a pull-down network coupled to a true wordline and to the true and complement bitlines. A pull-up network of a first bitcell is activated by the complement wordline. A pull-down network of a second bitcell is activated by the true wordline. A first value based on the pull-up network of the first bitcell and the pull-down network of the second bitcell is read using a sense amplifier coupled to a true bitline and a complement bitline. A PUF key is generated using the first value.
