Patent ID: 6956763

Claim:
A magnetoelectronics information device, comprising: a free magnetic region; a pinned magnetic region; and a tunneling barrier interposed between said free magnetic region and said pinned magnetic region, wherein magnetic moments of said free magnetic region and said pinned magnetic region that are adjacent to said tunneling barrier are oriented to provide a first magnetization state when: a first magnetic field with a first field magnitude is produced in proximity to the magnetoelectronics information device at a first time (t 1 ); a second magnetic field with a second field magnitude is produced in proximity to the magnetoelectronics information device at a second time (t 2 ); said first magnetic field is adjusted to provide a third field magnitude that is less than said first field magnitude and greater than zero at a third time (t 3 ); said second magnetic field is adjusted to provide a fourth field magnitude that is less than said second field magnitude at a fourth time (t 4 ); and said first magnetic field is adjusted to provide a fifth field magnitude that is less than said third field magnitude at a fifth time (t 5 ), wherein t 1 <t 3 <t 5 .
