Abstract
According to one embodiment, a memory device includes: a first variable resistance layer; first and second semiconductor layers being in contact with the first variable resistance layer; a first word line; a second word line being adjacent to the first word line; and a third word line being adjacent to the first and second word lines with the first semiconductor layer, the first variable resistance layer, and the second semiconductor layer interposed therebetween, and provided between the first word line and the second word line. In the first variable resistance layer, a first region including a shortest path connecting the first word line and the third word line functions as a first memory cell, and a second region including a shortest path connecting the third word line and the second word line functions as a second memory cell.
