Abstract
A semiconductor storage device includes first and second memory cells adjacent to each other in the X direction, each of the memory cells having a program transistor and a switch transistor. First and second nanosheets, which are to be channel regions of the program transistors, are exposed from first and second gate interconnects, respectively, at faces on the sides opposed to each other in the X direction. Third and fourth nanosheets, which are to be channel regions of the switch transistors, are exposed from third and fourth gate interconnects, respectively, at faces on the sides opposed to each other in the X direction.
