Abstract

According to one embodiment, in a semiconductor storage device, the first contact plug electrically connects the third region to the first drive circuit. The second contact plug is provided on one end side of a fourth region in the third direction, the fourth region arranged between the first separation film and the second separation film in the second conductive layer. The second contact plug electrically connects the fourth region to the first drive circuit. The third contact plug is provided on the other end side of the third region in the third direction. The third contact plug electrically connects the third region to the second drive circuit.
