HIGH VOLTAGE GENERATION CIRCUIT AND FLASH MEMORY DEVICE INCLUDING THE SAME

摘要

PURPOSE: A high voltage generating circuit and a flash memory device including the same capable of controlling voltage level are provided to increase efficiency without additional work. CONSTITUTION: A high voltage generating circuit(70) includes a high voltage detection unit(110), an oscillator, a pumping clock control unit, and a charge pump. The high voltage detection unit provides the comparison signal and compares the high voltage applied with the memory cell array with the reference voltage. The pumping signal control unit provides the clock control signal for changing the frequency of the clock signal in response to the comparison signal. The oscillator produces the clock signal in which the frequency changes according to the clock control signal.
