Abstract:
A method of writing to a magnetic random access memory cell includes applying an alternating current signal to the magnetic random access memory cell having a first magnetic orientation, and applying a direct current pulse to the magnetic random access memory cell to change the magnetic orientation of the magnetic random access memory cell from the first magnetic orientation to a second magnetic orientation. The first magnetic orientation and the second magnetic orientation are different.
