Claim 13:
14. A non-volatile memory device, comprising:
a negative voltage switching device, comprising:
a first switching circuit configured to transmit a first negative voltage;
a second switching circuit configured to transmit a second negative voltage; and
a switching selection circuit configured to select one of the first switching circuit or the second switching circuit for transmitting one of the first negative voltage and the second negative voltage to an output terminal;
a CG driver configured to receive the first negative voltage in a program mode and the second negative voltage in an erase mode using the negative voltage switching device;
a TG driver configured to receive the second negative voltage in the program mode and the first negative voltage in the erase mode using the negative voltage switching device; and
a non-volatile memory cell where an erase operation of the erase mode and a program operation of the program mode are performed by the CG driver and the TG driver, respectively.
