Abstract
Memory stacks, memory devices and method of forming the same are provided. A memory stack includes a spin-orbit torque layer, a magnetic bias layer and a free layer. The magnetic bias layer is in physical contact with the spin-orbit torque layer and has a first magnetic anisotropy. The free layer is disposed adjacent to the spin-orbit torque layer and has a second magnetic anisotropy perpendicular to the first magnetic anisotropy.
