STRUCTURE OF MAGNETIC MEMORY CELL AND MAGNETIC MEMORY DEVICE

摘要

A structure of magnetic memory cell including a first anti-ferromagnetic layer is provided. A first pinned layer is formed over the first anti-ferromagnetic layer. A tunneling barrier layer is formed over the first pinned layer. A free layer is formed over the tunneling barrier layer. A metal layer is formed over the free layer. A second pinned layer is formed over the metal layer. A second anti-ferromagnetic layer is formed over the second pinned layer.
