    Abstract: An apparatus includes circuits, a field line configured to generate a magnetic field based on an input, a sensing module configured to determine a parameter of each circuit, and a magnetic field direction determination module configured to determine an angular orientation of the apparatus relative to an external magnetic field based on the parameter. Each circuit includes multiple magnetic tunnel junctions. Each magnetic tunnel junction includes a storage layer having a storage magnetization direction and a sense layer having a sense magnetization direction configured based on the magnetic field. Each magnetic tunnel junction is configured such that the sense magnetization direction and a resistance of the magnetic tunnel junction vary based on the external magnetic field. The parameter varies based on the resistances of the multiple magnetic tunnel junctions. The magnetic field direction determination module is implemented in at least one of a memory or a processing device.

    Abstract: A circuit includes a magnetic logic unit including input terminals, output terminals, a field line, and magnetic tunnel junctions (MTJs). The field line electrically connects a first and a second input terminal, and is configured to generate a magnetic field based on an input to at least one of the first and the second input terminal. The input is based on an analog input to the circuit. Each MTJ is electrically connected to a first output terminal and a second output terminal, and is configured such that an output of at least one of the first and the second output terminal varies in response to a combined resistance of the MTJs. The resistance of each of the MTJs varies based on the magnetic field. The circuit is configured to generate an analog output based on the output of at least one of the first and the second output terminal.

    Abstract: A check engine includes a plurality of comparators each including a first directional characteristic aligned to store at least one reference bit included in a set of reference bits, and a second directional characteristic aligned to present at least one target bit included in a set of target bits. Each of the plurality of comparators is configured to produce an output representing a level of matching between the at least one target bit and the at least one reference bit, based on a relative alignment between the first directional characteristic and the second directional characteristic. The check engine is configured such that the outputs of the plurality of comparators are combined to produce a combined output. The check engine is configured to determine that the set of target bits matches the set of reference bits based on the combined output of the plurality of comparators.

    Abstract: An apparatus includes a circuit and a field line. The circuit includes a magnetic tunnel junction including a storage layer and a sense layer. The field line is configured to generate a magnetic field based on an input signal, where the magnetic tunnel junction is configured such that a magnetization direction of the sense layer and a resistance of the magnetic tunnel junction vary based on the magnetic field. The circuit is configured to amplify the input signal to generate an output signal that varies in response to the resistance of the magnetic tunnel junction.
