A circuit for controlling a non-volatile memory cell having a source, a drain, a control gate, and a bulk is disclosed. The control circuit comprises a voltage source, a first charge-pumping circuit, a word-line switch, a second charge-pumping circuit, a source switch, a third charge-pumping circuit, and a bulk switch. The first charge-pumping circuit, second charge-pumping circuit and third charge-pumping circuit respectively generate a first positive voltage, second positive voltage and negative voltage in response to the voltage source. The word-line switch selects and applies one of the voltage source or the first positive voltage to the control gate. The source switch selects and applies one of a ground potential or the second positive voltage to the source. The bulk switch selects and applies one of the ground potential or the negative voltage to the bulk. According to the present invention, the first positive voltage is applied to the control gate and the negative voltage is applied to the bulk during an erase operation.
