US Patent 10490730 Magnetic memory device with increased storage density

According to one embodiment, a magnetic memory device includes a conductive layer, first and second magnetic layers, a first nonmagnetic layer and a controller. The conductive layer includes first and second portions, and a third portion between the first and second portions. The first magnetic layer is separated from the third portion in a first direction crossing a second direction being from the first portion toward the second portion. The second magnetic layer is provided between the first magnetic layer and at least a portion of the third portion. The first nonmagnetic layer includes first and second regions. The first region is provided between the first and second magnetic layers. The second region is continuous with the first region. The second region overlaps at least a portion of the second magnetic layer in the second direction. The controller is electrically connected to the first and second portions.
