Claim 0:
1. A magnetic memory device comprising:
a plurality of first wirings each extending in a first direction;
a plurality of second wirings each extending in a second direction intersecting the first direction;
a plurality of first memory cells provided between the plurality of first wirings and the plurality of second wirings, each of the plurality of first memory cells including a first switching element and a first magnetoresistance effect element connected in series to each other, the first switching element being connected to a corresponding first wiring of the plurality of first wirings, and the first magnetoresistance effect element being connected to a corresponding second wiring of the plurality of second wirings; and
an interlayer insulating film,
wherein:
the first switching element includes a first bottom electrode provided on a first wiring side, a first top electrode provided on a first magnetoresistance effect element side, and a first switching material layer provided between the first bottom electrode and the first top electrode,
the first bottom electrode included in each of the first memory cells adjacent to each other in the first direction is continuously provided on the corresponding first wiring connecting the first memory cells adjacent to each other in the first direction,
the first memory cell further includes a sidewall insulating layer provided on sidewalls of the first top electrode and the first switching material layer of the first switching element,
the interlayer insulating film is provided directly on an entire side surface of the sidewall insulating layer,
the sidewall insulating layer is further provided on a sidewall of the first magnetoresistance effect element, and
the sidewall insulating layer is not provided on a sidewall of the first bottom electrode of the first switching element, and the interlayer insulating film is provided on the sidewall of the first bottom electrode of the first switching element.
