Abstract: Devices and methods for generating a random number that utilizes a magnetic tunnel junction are disclosed. An AC current source can be in electrical connection to a magnetic tunnel junction to provide an AC current to the magnetic tunnel junction. A read circuit can be used to determine a bit based on a state of the magnetic tunnel junction. A rate of production of the bits can be adjusted, such as by adjusting a frequency or amplitude of the AC current. A probability of obtaining a “0” or “1” bit can be managed, such as by an addition of DC biasing to the AC current.
