Abstract
A method and system provide and program a nonvolatile logic device. The nonvolatile logic device includes input and output magnetic junctions and at least one magnetic junction between the input and output magnetic junctions. The input magnetic junction includes an input junction free layer having an input junction easy axis. The input magnetic junction may be switchable using a current driven through the magnetic junction. The output magnetic junction includes an output junction free layer having an output junction easy axis. Each of the magnetic junction(s) includes a free layer having an easy axis. The input magnetic junction is magnetically coupled to the output magnetic junction through the magnetic junction(s). In some aspects, the method includes switching the magnetic moment(s) of the input magnetic junction from a first state to a second state, applying and then removing magnetic field(s) along the hard axis of the at least one magnetic junction.
