发明名称 Magnetic random access memory and a method for manufacturing thereof
摘要 Magnetic random access memory including a cell array stacked in a plurality of plane levels, a plurality of write wirings disposed on each of the stacked cell array, and a contact plug commonly or independently coupled to the plurality of stacked array planes. Also, a method for manufacturing magnetic random access memory so as to reduce influences of parasitic wiring resistances due to differences of the writing current values for supplying the stacked cell array. The magnetic random access memory includes a cell array of TMR elements stacked in a plurality of plane levels, a plurality of write wirings being formed so that a parasitic resistance becomes smaller accompanying a longer distance from a drive current source, and one or a plurality of contact plugs for commonly or independently coupling to the plurality of stacked array planes.
