Abstract
A true random number generator device based on a diffusive memristor is disclosed. The random number generator device includes a diffusive memristor driven by a pulse generator circuit. The diffusive memristor produces a stochastically switched output signal. A comparator circuit receives the stochastically switched output signal from the diffusive memristor and generates an output signal having a random pulse width. An AND gate logic circuit is driven by a clock signal and the output signal from the comparator circuit. The AND gate logic circuit produces a combined output signal. A counter circuit receives the combined output signal from the AND gate logic circuit and generates a random bit string output signal.
