Abstract
A method for controlling a magnetic memory device is provided. The method includes: applying a first control signal and a second control signal to a ferromagnetic fixed layer and a ferromagnetic free layer of the magnetic memory device respectively, wherein a first voltage level of the first control signal is lower than a second voltage level of the second control signal; sensing a first current signal flowing through the magnetic memory device; and determining a logical state of a first data bit according to the first current signal.
