| Zusammenfassung: | A magnetic memory device includes a pinned magnetic pattern, a tunnel barrier pattern, a free magnetic pattern, a diffusion barrier pattern, a non-magnetic pattern and a capping pattern, which are sequentially stacked on a substrate. The diffusion barrier pattern includes a first non-magnetic metal and oxygen. The non-magnetic pattern includes a second non-magnetic metal and oxygen. An oxide formation energy of the first non-magnetic metal is lower than an oxide formation energy of the second non-magnetic metal. |
