Patent ID: 8611145

Claim:
A method of writing to a spin-transfer torque magnetic 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 and a second neighboring MTJ to be substantially equal to zero, the STTMRAM cell including, a first transistor coupled to the first neighboring MTJ; a second transistor coupled to the second neighboring MTJ, the selected MTJ being coupled to both the first transistor and the second transistor, the first transistor and the second transistor each having a gate coupled to a respective word line; raising the voltage of the word line coupled to the gate of the first transistor to a first voltage and the voltage of the word line coupled to the gate of the second transistor to a second voltage, wherein a first current flows through the first transistor and a second current flows through the second transistor, the first and second currents flowing through the selected MTJ and further wherein the first current is smaller than the second current.
