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.
