Abstract:
1. A spin injection write type magnetic memory device comprising: a semiconductor substrate; a first gate electrode provided on a gate insulating film provided on the semiconductor substrate, and extending along a first direction; a first diffusion area and a second diffusion area formed on a surface of the semiconductor substrate and sandwiching the first gate electrode; a first plug provided on the first diffusion area; a second plug provided on the second diffusion area; a first magnetoresistance element provided on the second plug; a second gate electrode provided on a gate insulating film provided on the semiconductor substrate, and extending in parallel with the first gate electrode; a third diffusion area and a fourth diffusion area formed on the surface of the semiconductor substrate and sandwiching the second gate electrode, the first and second gate electrodes sandwiching the second and fourth diffusion areas, the fourth diffusion area and the second diffusion area being positioned in a line along the first direction; a third plug provided on the third diffusion area; a fourth plug provided on the fourth diffusion area; a second magnetoresistance effect element provided on the fourth plug; a first interconnect connected to upper surfaces of the first and third plugs; and a second interconnect connected to upper surfaces of the first and second magnetoresistance effect elements.
