Patent ID: 7851878

Claim:
A magnetic memory device comprising: a device isolation film confining an active region at a substrate having impurities of a first conductivity; a common line formed in the active region, the common line having impurities of a second conductivity; a first write-in semiconductor pattern, a readout semiconductor pattern and second write-in semiconductor pattern, which are each disposed on the common line, laterally separated from each other, and are each doped with impurities of the first conductivity; a magnetic tunnel junction structure electrically connected to the readout semiconductor pattern and disposed on the readout semiconductor pattern; first and second write-in conductors each disposed on the first and second write-in semiconductor patterns at both lateral sides of the magnetic tunnel junction structure, the first and second write-in conductors are each electrically connected to the first and second write-in semiconductor patterns; a readout line electrically connected to the magnetic tunnel junction structure; and first and second write-in lines each electrically connected to the first and second write-in conductors, wherein a programming operation is divisionally carried out through a first programming mode using a first electric field generated by the first write-in conductor and a second programming mode using a second electric field generated by the second write-in conductor, and wherein a direction of the first electric field is reversed to a direction of the second electric field.
