Patent ID: 7613035

Claim:
A method of writing into a magnetic memory device comprising: flowing a first write current to a first signal line; flowing a second write current to a second signal line, the second write current being directed opposite to the first write current; flowing a third write current to a third signal line; and memorizing a first memory information or a second memory information, based on directions of the first write current and the second write current, wherein the magnetic memory device including a memory cell including a first magnetoresistance effect element, a second magnetoresistance effect element having one terminal connected to one terminal of the first magnetoresistance effect element, and a select transistor connected to a connection node of the first magnetoresistance effect element and the second magnetoresistance effect element; the first signal line extended in a first direction and connected to the other end of the first magnetoresistance effect element; the second signal line extended in the first direction and connected to the other end of the second magnetoresistance effect element; and the third signal line extended in a second direction crossing the first direction, crossing the first signal line in a region where the first magnetoresistance effect element is formed, and crossing the second signal line in the region where the second magnetoresistance effect element is formed, wherein the magnetic memory device memorizes the first memory information with the first magnetoresistance effect element being in a high resistance state and the second magnetoresistance effect element being in a lower resistance state or the second memory information with the first magnetoresistance effect element being in the lower resistance state and the second magnetoresistance effect element being in the high resistance state.
