Abstract
Methods and apparatus for creating a physically unclonable function for SRAM are disclosed. An example method includes after applying a voltage to a memory array: determining a first duration between the applying of the voltage and a first output of a first bit cell, the first output corresponding to a first value stored in the first bit cell, and determining a second duration between the applying of the voltage and a second output of a second bit cell, the second output corresponding to a second value stored in the second bit cell. The example method further includes determining a function based on a comparison of the first duration and the second duration, the function to establish an identification of a circuit that includes the memory array.
