Title: Charge-pumping circuit
Inventor: KURIYAMA MASAO
IPC: G11C11/413
Filed: 2000-02-24
Granted: 2001-08-21
Abstract: A charge pumping circuit is disclosed, which can save current dissipation when the charge pump operation stops and shortens the time until the maximum output current can be obtained at the resetting time. When the charge pump operations stops, all capacitor node drive voltages of the charge pump circuit is fixed to the voltage near the potential of the boosting node. Normally, an output OSC signal of the oscillator for transferring the HI/LOW level is invalidated under the control for stopping the charge pump operation with the ENABLE signal. At this time, the charge pump circuit transfers the same level for controlling inverse flow control to each capacitor node. Namely, if the potential of voltage boosting node is a positive potential, it is HI level for driving the capacitor, and if the potential of voltage boosting node is a negative potential, it is LOW level for driving the capacitor. The charge pump circuit of the present invention is especially suitable for the power circuit of reading, writing, erasing operation of non-volatile semiconductor device.
