Abstract
A security primitive for an integrated circuit comprises an array of floating-gate transistors monolithically integrated into the integrated circuit and coupled to one another in a crossbar configuration. The floating-gate transistors have instance-specific process-induced variations in analog behavior to provide one or more reconfigurable physically unclonable functions (PUFs).
