Method and apparatus for sensing the state of a magnetic tunnel junction (MTJ)
Abstract:
A method of measuring the resistance of a magnetic tunnel junction (MTJ) is performed by selecting the MTJ to be measured, the MTJ having a resistance associated therewith and coupled to an access transistor. Further, measuring a voltage at an end of the MTJ that is coupled to the access transistor and measuring voltage, V0, at the coupling of the selected MTJ and the associated access transistor, turning off a decoder that is coupled to the MTJ, and after applying current, measuring the applied current and using the measured applied current to determine the resistance of the MTJ.
