Patent ID: 8514618

Claim:
A magnetic random access memory (MRAM) cell comprising a tunnel magnetic junction comprising a first ferromagnetic layer, a second ferromagnetic layer having a second magnetization that can be oriented relative to an anisotropy axis of the second ferromagnetic layer at a predetermined high temperature threshold, and a tunnel barrier between the first and second ferromagnetic layer; a first current line extending along a first direction and in communication with the magnetic tunnel junction; the first current line being configured to provide an magnetic field for orienting the second magnetization when carrying a field current; the MRAM cell being configured with respect to the first current line such that when providing the magnetic field, at least a component of the magnetic field is substantially perpendicular to said anisotropy axis; the second ferromagnetic layer having an asymmetrical shape along at least one of its dimension such that the second magnetization comprises a C-state pattern, and said C-state pattern being changeable into a S-state pattern by the second field component and the second magnetization being switchable by the first field component, when the magnetic field is provided.
