A magnetic random access memory capable of writing information with a
small write current is provided. A magnetic film or a multilayer magnetic
film of the present invention has a part where the magnetization
inversion is relatively easier than in the other parts. A magnetization
inversion mechanism of the magnetic film of the invention has an
application protrusion for applying a stronger magnetic field to a part
of the magnetic film than to the other parts thereof. The magnetic random
access memory of the invention includes a magnetoresistive film having
the multilayer magnetic film as a memory element or the magnetization
inversion mechanism as a writing unit.
