Abstract
In a semiconductor memory device, in a write operation performed to a memory cell transistor, a first voltage is applied to a first word line and a second voltage lower than the first voltage is applied to a second word line. When a stop command is received during the write operation, a third voltage lower than the second voltage is applied to the first and second word lines, thereafter a fourth voltage higher than the third voltage is applied to a first selection line, thereon or thereafter a fifth voltage higher than the fourth voltage is applied to the first and second word lines, thereafter a sixth voltage lower than the fourth voltage is applied to the first selection line, and thereafter a seventh voltage is applied to the first and second word lines.
