摘要
An apparatus includes circuits including a first circuit and a second circuit, each circuit including subarrays of magnetic tunnel junctions, where: (1) 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; and the subarrays are connected in series. The apparatus further comprises a field line configured to generate a first magnetic field for configuring an operating point of the first circuit based on a current flow through the field line, wherein impedance of one or more of the magnetic tunnel junctions in each of the plurality of rows of each subarray of magnetic tunnel junctions included in the first circuit is configured based on the first magnetic field.
