Abstract
A physically unclonable function generating system and related methods. Implementations may include comparing at least one physical parameter of a memory cell with a threshold value of the physical parameter and identifying a relationship of the at least one physical parameter of the memory cell to the threshold value. Implementations may also include associating one of a 0, 1, or X state to the memory cell based on the relationship of the at least one physical parameter to the threshold value and programming at least one state storage memory cell to store a programmed value corresponding with the associated 0, 1, or X state. Implementations may include including the programmed value of the at least one state storage memory cell in a PUF data stream.
