Abstract:
The disclosed technology relates to a multibit memory cell. In one aspect, the multibit memory cell includes a plurality of spin-orbit torque (SOT) tracks, plurality of magnetic tunnel junctions (MTJs), an electrically conductive path connecting a first MTJ and a second MTJ together, and a plurality of terminals. The plurality of terminals can be configured to provide a first SOT write current to the first MTJ, a second SOT write current to the second MTJ, and at least one of: the second SOT write current to a third MTJ, a third SOT write current to the third MTJ, and a spin transfer torque (STT) write current through the third MTJ. The junction resistances of the various MTJs are such that a combined multibit memory state of the MTJs is readable by a read current through all the MTJs in series.
