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: An apparatus includes groups of magnetic tunnel junctions, where the magnetic tunnel junctions in each group are arranged in rows, the magnetic tunnel junctions in each row are connected in series, and the rows are connected in parallel. The apparatus further includes a first conductive layer including conductive interconnects, a second conductive layer including straps, and a third conductive layer including field lines, each field line configured to generate a magnetic field for configuring an operating point of a corresponding subset of the magnetic tunnel junctions in each group based on a current flow through each field line. The magnetic tunnel junctions in each group are disposed between and connected to a corresponding one of the conductive interconnects and a corresponding one of the straps. The second conductive layer is disposed between the first conductive layer and the third conductive layer.
