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, while the other end of the magnetic metal layer is coupled to a first bit line. The magnetic sensing device can be coupled with a second bit line. 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.
