摘要： A magnetic memory cell is disclosed. The memory cell includes first conductor and second conductors coupled to first and second electrodes of a magnetic element. A plurality of memory cells is interconnected by first and second conductors to form a memory array or block. The second conductor is coupled to the second electrode via a conductive strap having a fuse portion. The fuse portion can be blown to sever the connection between the second conductor and magnetic element, Nitride.

摘要： Probes are electrically connected to a surface of a tunnel junction film stack comprising a free layer, a tunnel barrier, and a pinned layer. Resistances are determined for a variety of probe spacings and for a number of magnetizations of one of the layers of the stack. The probe spacings are a distance from a length scale, which is related to the Resistance-Area (RA) product of the tunnel junction film stack. Spacings from as small as possible to about 40 times the length scale are used. Beneficially, the smallest spacing between probes used during a resistance measurement is under 100 microns. A measured in-plane MagnetoResistance (MR) curve is determined from the “high” and “low” resistances that occur at the two magnetizations of this layer. The RA product, resistances per square of the free and pinned layers, and perpendicular MR are determined through curve fitting.
