High voltage switching circuit of nonvolatile memory device
A high-voltage switching circuit comprises: a high-voltage switch configured to transfer a high voltage; a pumping circuit configured to boost signals of first, second, and third nodes by conducting pumping operations in response to a plurality of clock signals; and a drive signal transmission circuit configured to boost the signal of the second node at a constant rate while maintaining a voltage level of the third node regardless of variation of a voltage level at the first node and transfer the boosted signal of the second node to the high-voltage switch, activating the high-voltage switch.
