Claim 0:
1. A magnetoresistive random access memory, comprising:
a substrate;
a conductive plug in said substrate, wherein said conductive plug has a notched portion on one side of the upper edge of said conductive plug;
a magnetic memory cell with a bottom electrode electrically connecting with said conductive plug, a magnetic tunnel junction on said bottom electrode and a top electrode on said magnetic tunnel junction, wherein a bottom surface of said magnetic memory cell and a top surface of said conductive plug completely align and overlap each other;
a conformal liner layer immediately on a surface of said notched portion and on sidewalls of said magnetic memory cell, wherein said conformal liner layer is not on a top surface of said top electrode; and
an overlying metal layer electrically connected with said top electrode, wherein said overlying metal layer contacts entire said top surface of said top electrode.
