摘要： A semiconductor device including a program voltage supply circuit that supplies a drain of a memory cell with a program voltage, a detection circuit that refers to an output voltage of the program voltage supply circuit and detects a decrease of the program voltage supplied thereby, a frequency converting circuit that generates the clock signal by converting a frequency of a clock signal generated by an oscillator circuit into a lower frequency when the program voltage supplied by the program voltage supply circuit becomes equal to or lower than a given voltage, and a voltage generating circuit that generates a voltage supplied to a gate of the memory cell by using a clock signal, the frequency of which is converted by the frequency converting circuit. It is therefore possible to make the best use of the ability of the program voltage generating circuit in programming.
