Abstract

A magnetic cell and method for providing the magnetic cell are described. A magnetic cell resides on a substrate and is usable in a magnetic device. The magnetic cell includes a magnetic junction and an ovonic threshold switch (OTS) layer. The magnetic junction has a plurality of sidewalls. The magnetic junction includes a free layer switchable between a plurality of stable magnetic states when a write current is passed through the magnetic junction, a nonmagnetic spacer layer and a pinned layer. The nonmagnetic spacer layer is between the pinned layer and the free layer. The OTS layer covers at least a portion of the plurality of sidewalls.
