PURPOSE: A high voltage generating circuit is provided to store a high voltage by designing differently the volume of capacitors for a charge pump based on the volume of a pre-charged voltage in order to reduce the size of the circuit. CONSTITUTION: A pump state generates a high voltage signal according to an input voltage, a first and a second clock signals. A first pump stage(110) pumps a first voltage and stores the first voltage in a first capacitor(C1). The first voltage is transmitted to a second pump stage(120). The second pump stage pumps a second voltage which is larger than the first voltage and stores the second voltage in a second capacitor(C2). The volume of the second capacitor is large than the volume of the first capacitor. |
