Abstract:
1. A method of writing to a spin-torque transfer memory random access memory (STTMRAM) cell of an STTMRAM array comprising: setting the voltage of a bit line that is coupled to a selected magnetic tunnel junction (MTJ) to be substantially equal to a voltage Vcc; setting the voltage of a sense line (SL) that is coupled to a first neighboring MTJ to be substantially equal to zero, the first neighboring MTJ being coupled to a first transistor, the selected MTJ being coupled to a second transistor, the first and second transistors each having a gate coupled to a respective word line; maintaining the voltage of bit lines and sense lines coupled to the MTJs of the STTMRAM array, other than the bit line and sense line that are coupled to the selected MTJ and the first neighboring MTJ, substantially equal to the voltage Vcc; and raising the voltage of each of the word lines coupled to the gates of the first and second transistor to a voltage that is equal to or higher than the voltage Vcc to program the selected MTJ.
