Abstract
A magnetic device configured to perform an analog adder circuit function and including a plurality of magnetic units. Each magnetic unit includes n magnetic tunnel junctions electrically connected in series via a current line. Each magnetic tunnel junction includes a storage magnetic layer having a storage magnetization, a sense magnetic layer having a sense magnetization, and a tunnel barrier layer. Each magnetic unit also includes n input lines, each being configured to generate a magnetic field adapted for varying a direction of the sense magnetization and a resistance of the n magnetic tunnel junctions, based on an input. Each of the n magnetic units is configured to add said n inputs to generate an output signal that varies in response to the n resistances.
