Abstract

A semiconductor device includes a device magnetic tunnel junction (MTJ) and sensor MTJs. A spin polarization of a free layer of the device MTJ is configurable based at least in part on electrical energy supplied to the device MTJ. A spin polarization of a corresponding free layer of each sensor MTJ is configurable based at least in part on a magnetic field created by the spin polarization of the free layer of the device MTJ. A circuit disposed is in electrical communication with the plurality of sensor MTJs and configured to determine the corresponding free layer spin polarizations of each of the sensor MTJs based at least in part on electrical energy supplied to the sensor MTJs by the circuit. The circuit is configured to determine a magnetoresistance of the device MTJ based at least in part on the determined corresponding free layer spin polarizations of the sensor MTJ.
