An electrostatic discharge protection circuit protects an internal circuit that is coupled to a pad from electrostatic discharge damage. The electrostatic discharge protection circuit comprises at least one silicon-controlled rectifier and an erasable programmable read only memory. The silicon-controlled rectifier is configured with an anode and a cathode connected to the pad and a grounding node, respectively. The erasable programmable read only memory is configured with a drain connected to the pad, a source connected to the grounding node, and a control gate connected to the grounding node. Accordingly, the erasable programmable read only memory enters breakdown to be programmed and triggers the silicon-controlled rectifier to conduct a current when electrostatic discharge stress occurs at the pad.
