Abstract
A semiconductor device according to an embodiment includes first and second drain select transistors, first and second source select transistors, first and second memory cell transistors, third and fourth memory cell transistors, first and second bit lines, first to third select gate line, first and second word lines, and a controller. The controller is configured to execute, in the program loop, a program operation, a recovery operation and a verify operation in sequence. In the write operation of the first memory cell transistor, the controller is configured, at a first time of the recovery operation, to: apply a first voltage to the first select gate line; apply a second voltage to the third select gate line; and apply a third voltage to the first bit line.
