Abstract
According to one embodiment, a nonvolatile semiconductor memory device includes memory cells storing data in a nonvolatile manner, word lines connected to the memory cells and including a first word line and a second word line which is n-th (n is an integer of 1 or more) from the first word line, and a control circuit configured to control a voltage of a word line to write data to a memory cell so that data are written in order from the first word line to the second word line. In a write sequence of the first word line, the control circuit applies a writing voltage to the second word line before writing a memory cell connected to the first word line.
