A method of reading a memory cell of a magneto-resistive random access memory device, wherein the memory cell has a ferromagnetic free layer having a first magnetization orientation and a ferromagnetic reference layer, includes applying a first read current from the ferromagnetic free layer to the ferromagnetic reference layer and storing a first voltage generated by the memory cell in response to the first read current, generating a magnetic field adjacent to the memory cell, the magnetic field having a second magnetization orientation that is not parallel to the first magnetization orientation, while the magnetic field is being generated, applying a second read current from the ferromagnetic free layer to the ferromagnetic reference layer and storing a second voltage generated by the memory cell in response to the second read current, and determining a state of the memory cell based on the first voltage and the second voltage.
