Abstract
A magnetic memory device includes a three-terminal type memory cell. A first terminal is connected to a first conductor layer. A second terminal is connected to a second conductor layer. A third terminal is connected to a third conductor layer. The memory cell includes a fourth conductor connected to the first conductor layer, the second conductor layer, and the third conductor layer. A magnetoresistance effect element of the memory cell is coupled between the third conductor layer and the fourth conductor layer. A first switching element is coupled to the second conductor layer and the fourth conductor layer. A second switching element coupled to the first conductor layer and the third conductor layer. The fourth conductor layer includes a first ferromagnetic layer and a first non-magnetic layer. The first non-magnetic layer comprises at least one of ruthenium, iridium, rhodium, or osmium.
