摘要:
Apparatuses, systems, and methods are disclosed for magnetoresistive random access memory. A magnetic tunnel junction for storing data includes a fixed layer, a barrier layer, and a composite free layer. A barrier layer is disposed between a fixed layer and a composite free layer. A composite free layer includes a ferromagnetic amorphous layer and an in-plane anisotropy free layer. A spin Hall effect (SHE) layer may be coupled to the composite free layer of the magnetic tunnel junction. The SHE layer may be configured such that an in-plane electric current within the SHE layer causes a spin current in the composite free layer.
