A magnetic memory device includes a memory cell which has a first wiring
line composed of a first wiring layer, a second wiring line composed of a
second wiring layer and provided above or below the first wiring line so
as to cross the first wiring line, and a magnetoresistive effect element
device provided in a position where the first wiring line and the second
wiring line cross each other. The device further includes a peripheral
circuit which includes a third wiring line provided around the memory
cell and composed of the first wiring layer, a fourth wiring line
provided above or below the third wiring line and composed of the second
wiring layer, and at least one magnetic layer forming the
magnetoresistive effect element device and provided between the third
wiring line and the fourth wiring line.
