Claim Text:
1. A semiconductor storage device, comprising: a memory cell array region in which a plurality of storing MTJ elements capable of changing resistance depending on a direction of magnetization are arranged on a semiconductor substrate; and a resistive element region in which a plurality of resisting MTJ elements are arranged on the semiconductor substrate along a first direction and a second direction perpendicular to the first direction, wherein an area of a first cross section of the resisting MTJ element, the first cross section parallel with an upper surface of the semiconductor substrate, is sufficiently larger than an area of a second cross section of the storing MTJ element, the second cross section also parallel with the upper surface of the semiconductor substrate, to prevent flux reversal of the resisting MTJ element, the storing MTJ element and the resisting MTJ element each comprises a free layer whose direction of magnetization is inverted by a spin transfer torque, and the second direction is perpendicular to the first direction in an upper surface of the semiconductor substrate.
