ABSTRACT:
A nonvolatile semiconductor memory according to the present invention includes a memory cell transistor which is disposed in a first region and which has a gate electrode of a stacked structure, and a dummy cell which is disposed in a second region neighboring the first region and which has a gate electrode having the same structure as that of the gate electrode of the memory cell transistor. The memory cell transistor and dummy cell are connected to the same word line. The memory cell transistor has a diffusion layer serving as the source/drain region thereof, while the dummy cell does not have the diffusion layer serving as the source/drain region thereof.
