  • Publication number: 20100023287
    Abstract: 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.

  • Patent number: 7453747
    Abstract: A method and apparatus for minimizing errors that may occur when writing information to a magnetic memory cell array with an operating write current due to changes in the local magnetic fields and. A test write current is sent to a reference memory cell and the effect of the test current on the orientation of the magnetization in the reference cell is monitored. The write current is then modified to compensate for any changes in the optimum operating point that have occurred. Arrays of reference magnetic memory cells having varying properties may be used to more accurately characterize any changes that have occurred in the operating environment. A phase difference between a time varying current used to drive the reference cell and the corresponding variations in the orientation of the magnetization in the reference cell may also be used to further characterize changes in the operating environment.

  • Publication number: 20080256090
    Abstract: In a network of computer nodes, a directory service provides both the physical location of directory information around the network and the directory information itself in a single data structure. This single data structure is distributed throughout the network, and continuously redistributed, so as to create a directory service that is both more flexible, and more robust, than prior art directory services.
