ABSTRACT:
A method of performing a thermally assisted write operation on a selected two conductor spin valve memory (SVM) cell having a material wherein the coercivity is decreased upon an increase in temperature. In a particular embodiment, a first write magnetic field is established by a first write current flowing from a first voltage potential to a second voltage potential as applied to the first conductor. A second write magnetic field is established by a second write current flowing from a third voltage potential to a fourth voltage potential as applied to the second conductor. The voltage potential of the first conductor is greater than the voltage potential of the second conductor. As a result, a third current, flows from the first conductor through the SVM cell to the second conductor. The SVM cell has an internal resistance such that the flowing current generates heat within the SVM cell. As the SVM cell is self heated, the coercivity of the SVM cell falls below the combined write magnetic fields.
