ABSTRACT:
A nonvolatile semiconductor memory according to an aspect of the invention includes a memory cell array and a power supply circuit. The memory cell array includes memory cells each having an insulating film and being programmed to store information by inflicting an electric stress on the insulating film to break the insulating film. The power supply circuit supplies to the memory cell a program voltage for the electric stress depending on a negative temperature coefficient the electric stress.
