ABSTRACT:
A device for discharaging static electricity protects an internal circuit against an electrostatic current. The device includes a discharge part which is connected between an input/output pad and a ground voltage line to form a discharge path discharging an electrostatic current introduced from an input/output pad; and an amplification circuit which is connected in parallel with the discharge part and supplies a sense amplification signal generated by amplifying the electrostatic current as a control signal of the discharge part.
