Abstract

An apparatus and method for providing a source of random numbers are generally described. In one example, an apparatus includes one or more storage elements having a selected voltage and a trip point, the voltage being close enough to the trip point such that random telegraph signal (RTS) noise associated with the elements is a determinant of whether the read voltage is above or below the trip point.
