Abstract
The present invention suppresses short circuits of a magnetic memory cell and a deterioration of the characteristics of a magnetic layer. A magnetic memory cell includes: a data storage layer; a tunnel barrier layer formed on the data storage layer; a reference layer formed on the tunnel barrier layer so as to cover a part of the tunnel barrier layer; and a metallic oxide layer formed on the tunnel barrier layer without covering the reference layer. The metallic oxide layer contains an oxide of a material of a contact part of the reference layer with the tunnel barrier layer.
