Patent ID: 7088608

Claim:
A method comprising: applying a first current pulse having a first current level to a strip line of a magneto resistive memory cell; and applying a second current pulse having a second current level to the strip line of the magneto resistive memory cell, wherein the second current level is higher than the first current level; wherein the first magnetic field failed to write a desired value to the magneto resistive memory cell, wherein the second magnetic field is stronger than the first magnetic field and wherein the magneto resistive memory cell is one of a plurality of magneto resistive memory cells arrayed with a plurality of rows and a plurality of columns; and wherein the strip line is one of a digit line for a plurality of magneto resistive memory cells, a row line for a plurality of magneto resistive memory cells, a bit line for a plurality of magneto resistive memory cells, or a column line for a plurality of magneto resistive memory cells.
