Abstract: An apparatus includes a circuit including multiple magnetic tunnel junctions, the circuit configured to convert a quadrature modulated magnetic field to a quadrature modulated electrical signal, each magnetic tunnel junction including a storage layer having a storage magnetization and a sense layer having a sense magnetization, each magnetic tunnel junction being configured such that the sense magnetization and impedance of each magnetic tunnel junction vary in response to the quadrature modulated magnetic field. The apparatus further includes a module configured to demodulate the quadrature modulated electrical signal to recover a signal encoded in the quadrature modulated magnetic field.

Abstract: An apparatus has a reference magnetic tunnel junction with a high aspect ratio including a reference layer with magnetization along a minor axis and a storage layer with magnetization along a major axis. The storage layer magnetization is substantially perpendicular to the magnetization along the minor axis. The magnetization orientation between the minor axis and the major axis is maintained by shape anisotropy caused by the high aspect ratio.

Abstract: An apparatus has magnetic logic units a logic circuit configured to receive a serial input bit stream at an input node. Individual bits of data from the serial input bit stream are serially written into individual magnetic logic units without buffering the serial input bit stream between the input node and the individual magnetic logic units. Individual bits of data from individual magnetic logic units are serially read to produce a serial output bit stream on an output node without buffering the serial output bit stream between the individual magnetic logic units and the output node.

Abstract: An apparatus includes circuits and a module configured to determine an external magnetic field based on a parameter of each circuit. Each circuit includes an array of magnetic tunnel junctions partitioned into subarrays. The magnetic tunnel junctions in each subarray are arranged in rows, the magnetic tunnel junctions in each row are connected in series, and the rows are connected in parallel. The subarrays are connected in series. Each magnetic tunnel junction includes a storage layer having a storage magnetization and a sense layer having a sense magnetization. Each magnetic tunnel junction is configured such that the sense magnetization and impedance of each magnetic tunnel junction vary in response to an external magnetic field. The parameter of each circuit varies based on a combined impedance of the multiple magnetic tunnel junctions. The 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 a first analog input to the circuit. Each MTJ is electrically connected to a first 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 the MTJs varies based on the magnetic field. The circuit is configured to mix the first analog input and a second analog input to generate an analog output based on the output of the second output terminal.

Abstract: A device has a flexible substrate supporting an array of magnetic sensors exposed to a uniform external magnetic field. One or more controllers receive magnetic sensor signals from the magnetic sensors. The one or more controllers collect reference magnetic sensor signals when the flexible substrate is aligned with the uniform external magnetic field. The one or more controllers collect first polarity magnetic sensor signals in response to deformation of the flexible substrate in a first direction. The one or more controllers collect second polarity magnetic sensor signals in response to deformation of the flexible substrate in a second direction. The magnetic sensor signals establish a profile of the orientation of the flexible substrate with respect to the uniform external magnetic field.
