Abstract

In a magnetic random access memory for generating an inductive magnetic flux by passing current into write wirings disposed closely to MTJ elements, whose resistance values varying depending on the magnetization array state of two magnetic layers of MTJ elements including two magnetic layers that hold a non-magnetic layer correspond to the stored information of “0”/“1”, and writing information by varying the magnetization direction of a free layer of the MTJ elements, the shape of the MTJ elements is warped so as to coincide substantially with the magnetic field curve generated from the write wirings.
