Abstract: A magnetic memory (MRAM) cell, comprising: a first layer formed from a substantially electrically conductive material; and a magnetic tunnel junction (MTJ) stack formed over the first layer, wherein the MTJ stack comprises: a ferromagnetic reference layer having an in-plane reference magnetization; a tunnel barrier layer; and a ferromagnetic storage layer between the tunnel barrier layer and the first layer, the storage layer having an in-plane storage magnetization; wherein the MTJ stack comprises an arrangement for providing an in-plane uniaxial anisotropy in the storage layer; wherein said in-plane uniaxial anisotropy makes an angle with the direction of the write current that is between 5° and 90°, and wherein said in-plane uniaxial anisotropy has an energy between 40 and 200 kBT and wherein coercivity is larger than 200 Oe.

Abstract: A memory device may comprise a substrate defining a main plane; a plurality of memory cells each comprising a SOT current layer disposed in the main plane of the substrate and a magnetic tunnel junction residing on the SOT current layer; and a bit line and a source line to flow a write current in a write path including the SOT current layer of a selected memory cell. The source line comprises a conductive magnetic material providing a magnetic bias field extending to the magnetic tunnel junction of the selected memory cell for assisting the switching of the cell state when the write current is flowing.
