Abstract
A random number generator device that utilizes a magnetic tunnel junction. An AC current source is in electrical connection to the magnetic tunnel junction to provide an AC current having an amplitude and a frequency through the free layer of the magnetic tunnel junction, the AC current configured to switch the magnetization orientation of the free layer via thermal magnetization. A read circuit is used to determine the relative orientation of the free layer magnetization in relation to the reference layer magnetization orientation.
