Abstract
Described is a physically unclonable functional circuit comprising: a resistive memory device (e.g., an MTJ device) having at least two terminals; a transistor coupled to one of the at least two terminals of the resistive memory device; and an analog-to-digital converter (ADC) having an input coupled to the one of the at least two terminals of the resistive memory device.
