Abstract:
1. A nonvolatile magnetic memory device having a nonvolatile magnetic memory array comprising; (A) write-in word line(s) that is (are) M (M≧1) in number, extending in a first direction, (B) bit lines that are N (N≧2) in number, extending in a second direction different from the first direction, and (C) tunnel magnetoresistance devices, each being formed in an overlap region of the write-in word line and the bit line and having a stacking structure of a first ferromagnetic layer, a tunnel barrier and a second ferromagnetic layer, the first ferromagnetic layer being electrically insulated from the write-in word line, and the second ferromagnetic layer being electrically connected to the bit line, wherein: when data is written into the tunnel magnetoresistance device positioned in the overlap region of the m-th-place write-in word line (m is one of 1, 2, . . . M) and the n-th-place bit line (n is one of 1, 2, . . . N), a current I(m) a spatial FIR filter assuming magnetic fields, which are supposed to be formed in the n-th-place bit line and the bit lines that are K in number by the current I(n) the coefficients g(
