Abstract:
A nonvolatile semiconductor memory device comprises: a plurality of first memory strings; a first select transistor having one end thereof connected to one end of the first memory strings; a first line commonly connected to the other end of a plurality of the first select transistors; a switch circuit having one end thereof connected to the first line; and a second line commonly connected to the other end of a plurality of the switch circuits. The switch circuit controls electrical connection between the second line and the first line.
