Abstract:
A nonvolatile semiconductor memory includes a cell unit having a select gate transistor and a memory cell connected in series, a select gate line connected to the select gate transistor, and a word line connected to the memory cell. One end of the word line is bent to the select gate line side, and a fringe is connected between a bent point and a distal end of the word line.
