Claim:
1. A device comprising: one or more resistive random access memory (Re RAM) elements; a random number generator configured to generate a random number dependent on an impedance value of at least one ReRAM element of the one or more ReRAM elements; and a control circuit configured to provide a programming signal to the at least one ReRAM element of the one or more ReRAM elements to configure an impedance value of the at least one ReRAM element of the one or more ReRAM elements, wherein the control circuit is further configured to vary at least an amplitude of the programming signal or a pulse width of the programming signal, or a combination thereof, to alter a degree of randomness of impedance values of the one or more ReRAM elements.
