Patent ID: 7245523

Claim:
Magnetic memory cell apparatus comprising: first, second and third electrical conductors; a first conductive path for carrying current flow bidirectionally between the first and second conductors; a first magnetic material in magnetic communication with the first conductive path, the first magnetic material being magnetizable in first or second different magnetic material directions, selectably in response to current flow in first or second opposite current flow directions, respectively, in the first conductive path; a magnetic device having an active layer of magnetic material disposed relative to the first magnetic material such that the active layer is magnetizeable in first or second different active layer directions, at least partially in response to magnetization of the first magnetic material in respectively the first or second magnetic material directions, the magnetic device further having a fixed magnetic layer parallel to the active layer; a second conductive path for carrying a sense current between the third conductor and the first conductor, serially through both the fixed magnetic layer and the active layer of the magnetic device.
