Abstract
A width and a thickness of a bit line are represented as Wand T, respectively, a thickness of a digit line is represented as T, and a distance from a center of the digit line in a thickness direction to a center of a free layer of an MTJ element in the thickness direction is represented as L. A width of the digit line is represented as W, and a distance from a center of the bit line in the thickness direction to the center of the free layer of the MTJ element in the thickness direction is represented as L. The distances Land Land the cross-sectional areas Sand Sare set in such a manner that when L/L1, a relation of (⅓)·(L/L)≦S/S≦1 is satisfied and when L/L≦1, a relation of 1≦S/S≦3(L/L) is satisfied.
