    摘要: A magnetic memory device may include a first vertical magnetic layer, a non-magnetic layer on the first vertical magnetic layer, and a first junction magnetic layer on the non-magnetic layer, with the non-magnetic layer being between the first vertical magnetic layer and the first junction magnetic layer. A tunnel barrier may be on the first junction magnetic layer, with the first junction magnetic layer being between the non-magnetic layer and the tunnel barrier. A second junction magnetic layer may be on the tunnel barrier with the tunnel barrier being between the first and second junction magnetic layers, and a second vertical magnetic layer may be on the second junction magnetic layer with the second junction magnetic layer being between the tunnel barrier and the second vertical magnetic layer.

    摘要: According to a method of fabricating the semiconductor memory device, a contact plug can be protected while mold openings are formed. A semiconductor memory device may include a mold dielectric layer on an entire surface of a substrate, the substrate including a first region and a second region. A contact plug may be provided in a contact hole formed through the mold dielectric layer in the first region. A variable resistor may be provided in a mold opening foamed through the mold dielectric layer in the second region. An upper surface of the contact plug may be at a level equal to or lower than an upper surface of the mold dielectric layer.
