Claim Text:
1. An apparatus, comprising: a plurality of circuits, each of the plurality of circuits including multiple magnetic tunnel junctions, each magnetic tunnel junction including a storage layer having a storage magnetization direction and a sense layer having a sense magnetization direction; a field line configured to generate a magnetic field based on an input, wherein: a sensing module configured to determine a parameter of the each of the plurality of circuits, wherein the parameter of the each of the plurality of circuits varies based on the resistances of the multiple magnetic tunnel junctions included in the each of the plurality of circuits; and a magnetic field direction determination module configured to determine an angular orientation of the apparatus relative to the external magnetic field based on the parameter of the each of the plurality of circuits, the magnetic field direction determination module being implemented in at least one of a memory or a processing device.
