Original Abstract Submitted
According to embodiments, a semiconductor memory device includes a memory string including a first select transistor, a first memory cell, and a second memory cell, a bit line, a first word line, a second word line, and a control circuit configured to execute a write operation including a program operation and a program verify operation. The control circuit is configured to raise a voltage of the second word line to a first voltage based on a first condition, in a case of executing the program verify operation of the first memory cell, and to raise a voltage of the first word line to the first voltage based on a second condition different from the first condition, in a case of executing the program verify operation of the second memory cell.
