1. A memory structure comprising:
a bottom electrode embedded in a first interconnect dielectric material layer;
a non-magnetic pedestal structure located on the bottom electrode and a portion of the first interconnect dielectric material layer;
a seeding area having a first width and located on the non-magnetic pedestal structure, wherein the seeding area comprises at least a tunnel barrier seed layer;
a chemical templating layer located on the seeding area;
a magnetic tunnel junction (MTJ) structure having a second width and located on the chemical templating layer, wherein the second width is less than the first width;
a top electrode located on the MTJ structure; and
a layer of non-oxidized metallic residue located on at least a sidewall of the tunnel barrier seed layer and intentionally shunting at least the seeding area.
