Abstract:
A semiconductor storage device includes first and second wirings that are in a first layer above the substrate, extend along a first direction, and are adjacent to each other along a second direction, third and fourth wirings that are in a second layer above the first layer, extend along the second direction, and are adjacent to each other along the first direction, first and second memory cells on the first wiring, and a third memory cell on the second wiring. The first to third memory cells each include a variable resistance element and a switching element. The switching element of the first memory cell includes a gate coupled to the third wiring. The switching elements of the second and third memory cells each include a gate coupled to the fourth wiring. The variable resistance elements of the first to third memory cells are formed with equal distances from each other.
