A magnetic random access memory includes a magnetoresistive element which has
a
recording layer, a fixed layer, and a tunnel barrier layer arranged between the
recording layer and the fixed layer, the fixed layer comprising an anti-ferromagnetic
layer, a first ferromagnetic layer which is in contact with the anti-ferromagnetic
layer, a second ferromagnetic layer which is magnetically coupled with the first
ferromagnetic layer by first magnetic coupling, a third ferromagnetic layer which
is magnetically coupled with the second ferromagnetic layer by second magnetic
coupling, a first nonmagnetic layer which is formed between the first and second
ferromagnetic layers, and a second nonmagnetic layer which is formed between the
second and third ferromagnetic layers and has a thickness different from a thickness
of the first nonmagnetic layer.
