Abstract
A semiconductor device is configured to implement a security protocol. The semiconductor device includes an entropy source that includes a plurality of bitcells. The entropy source is configured to output a sequence of physical unclonable function bit values based on intrinsic properties of the plurality of bitcells to generate a unique device secret for the security protocol, and selectively damage at least a portion of the plurality of bitcells to prevent reverse engineering the sequence of physical unclonable function bit values.
