  • Low power consumption charge pump system and associated control circuit and method for non-volatile memory cell array
    Patent number: 9245596
    Abstract: A charge pump system includes a logic circuit, a signal processing circuit, a charge pump circuit, a switching circuit, a first controllable discharge path, and a second controllable discharge path. The logic circuit receives a program enabling signal and generates a first control signal. The signal processing circuit receives a pump enabling signal, and generates a second control signal and a third control signal. The charge pump circuit receives the third control signal and generates an output signal. The switching circuit has a control terminal receiving the third control signal, a first terminal connected with the output terminal of the charge pump circuit, and a second terminal connected with a reservoir capacitor. The first controllable discharge path receives the first control signal, and the second controllable discharge path receives the second control signal.
