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 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 device has magnetic sensors and magnets in an array on a flexible substrate. Each magnetic sensor is sensitive to immediately proximate magnets. At least one controller evaluates magnetic sensor signals from the magnetic sensors produced in response to deformation of the flexible substrate.
