Abstract
A semiconductor device includes a program voltage supply circuit that supplies a drain of a memory cell with a program voltage, and a pull-down circuit that pulls down a potential of an output of the program voltage supply circuit in accordance with a current that flows in a data bus line connected to the memory cell. The semiconductor device may include a program voltage restrain circuit that restrains an intensity of supply of the program voltage by the program voltage supply circuit.
