Abstract: An apparatus for generating a magnetic field including permanent magnets arranged in a plane, each magnet being spatially separated along the plane from the adjacent magnet by a predetermined spacing, each magnet having a magnetic polarity opposed to the polarity of the adjacent magnet such that a magnetic field of adjacent magnets is oriented substantially perpendicular to the plane and in opposite directions, each magnet being spatially separated in the plane from the adjacent magnet by a nonmagnetic material. A method for programming a magnetic device or sensor device using the apparatus is also described.

Abstract: The present disclosure concerns a self-referenced magnetic random access memory-based ternary content addressable memory (MRAM-based TCAM) cell comprising a first and second magnetic tunnel junction; a first and second conducting strap adapted to pass a heating current in the first and second magnetic tunnel junction, respectively; a conductive line electrically connecting the first and second magnetic tunnel junctions in series; a first current line for passing a first field current to selectively write a first write data to the first magnetic tunnel junction; and a second current line for passing a write current to selectively write a second write data to the second magnetic tunnel junction, such that three distinct cell logic states can be written in the MRAM-based TCAM cell.
