Abstract
A magnetoresistive random-access memory (MRAM) device is disclosed. The device described herein has a thermal stability enhancement layer over the free layer of a magnetic tunnel junction. The thermal stability enhancement layer improves the thermal stability of the free layer, increases the magnetic moment of the free layer, while also not causing the magnetic direction of the free layer to become in plan. The thermal stability enhancement layer can be comprised of a layer of CoFeB ferromagnetic material.
