Abstract:
1. A magnetic memory device comprising: a read line to which read current is passed; first and second write lines disposed separately from the read line so that write current can be passed in two ways to each of the first and second write lines, where a parallel portion in which the first and second write lines extend parallel with each other is formed by bending at least one of the first and second write lines; and a magnetoresistive device having a magneto-sensitive layer whose magnetization direction changes according to a magnetic field applied, and disposed in the parallel portion, wherein at least one of the first and second write lines is formed in a loop shape so as to include a bent portion and first and second portions connecting the bent portion and both ends, the magnetization direction of the magneto-sensitive layer changes according to a magnetic field generated by write current flowing in the parallel portion, and information is written.
