ABSTRACT:
An MRAM cell comprises a magnetic metal layer and a magnetic sensing device in close proximity to the magnetic metal layer. One end of the magnetic metal layer is coupled with a word line transistor and a diode is included and configured to couple the magnetic sensing device to a bit line via a second word line transistor. The magnetic metal layer can be used to both program and read the cell, eliminating the need for a second current lien in the cell.
