  • Publication number: 20230335171
    Abstract: A method of manufacturing an array of magnetic random access memory cells includes writing to a magnetic random access memory cell. The writing to a memory cell includes determining an optimum write current for the array of memory cells, and applying the optimum write current to a first memory cell in the array. A first read current is applied to the first memory cell to determine whether a magnetic orientation of the first memory cell has changed in response to applying the optimum write current. A second write current is applied to the first memory cell when the magnetic orientation of the first memory cell has not changed. The second write current is different from the optimum write current. A second read current is applied to the first memory cell to determine whether the magnetic orientation of the first memory cell changed in response to applying the second write current.
