Claim:
1. A method of programming a magnetoresistive tunnel junction (MTJ) coupled to a transistor, the transistor having a gate, a source, and a drain, the method comprising: booting the voltage of a word line (WL) to a voltage substantially of Vddx volts, Vddx being substantially the sum of Vdd voltage and Vx voltage, the Vx voltage being greater than 0 volts and less than Vdd volts; setting the voltage of a bit line (BL) to substantially the Vdd volts, the BL coupled to an end of the MTJ, the drain of the access transistor being coupled to an opposite end of the MTJ, a source line (SL) coupled to the source of the access transistor; raising the SL to be substantially at Vx volts; and programming the MTJ to a parallel state.
