Abstract
A writing method for a magnetic memory cell which has a magnetic free stack layer with a bi-directional easy axis. A magnetic X axis and a magnetic Y axis are taken as reference directions, and the bi-directional easy axis is substantially on the magnetic X axis. The method includes applying a first magnetic field in a first direction of the magnetic Y axis. Then, a second magnetic field added onto the first magnetic field is applied in a first direction of the magnetic X axis. Next, the application of the first magnetic field is terminated. Thereafter, a third magnetic field is applied on the magnetic Y axis in a second direction opposite to the first direction. The second magnetic field is terminated and the third magnetic field is terminated.
