Abstract: The present invention describes an electrostatic discharge protection circuit that protects an internal circuit of a semiconductor device from electrostatic discharge. The electrostatic discharge protection circuit includes a first electrostatic protection unit that transfers static electricity as a driving signal and also discharges the static electricity to a first discharge line when the static electricity is generated in a pad. It also includes a second electrostatic protection unit that discharges the static electricity generated in the pad to a second discharge line in response to the driving signal transferred from the first electrostatic protection unit. Since the first electrostatic protection unit performs an electrostatic discharge operation and at the same time aids the driving of the second electrostatic protection unit, electrostatic discharge performance can be enhanced while a layout area of the electrostatic discharge protection circuit can be reduced.
