    摘要: Provided are a magnetic memory device and a method of forming the same. The magnetic memory device includes a pinned pattern including a coupling enhancement pattern, a polarization enhancement pattern, and a texture blocking pattern located between the coupling enhancement pattern and the polarization enhancement pattern, a free pattern located on the polarization enhancement pattern of the pinned pattern, and a tunnel barrier located between the pinned pattern and the free pattern. The coupling enhancement pattern includes a first enhancement magnetic pattern, a second enhancement magnetic pattern, and a first enhancement non-magnetic pattern located between the first enhancement magnetic pattern and the second enhancement magnetic pattern.
