Abstract
A method of generating a non reversible state at a bitcell having a first magnetic tunnel junction (MTJ) and a second MTJ includes applying a program voltage to the first MTJ of the bitcell without applying the program voltage to the second MTJ of the bitcell. A memory device (102) includes a bitcell having a first MTJ (106) and a second MTJ (108) and programming circitry (104) configured to generate a non reversible state at the bitcell by applying a program signal to a selected one of the first MTJ and the second MTJ of the bitcell.
