Patent ID: 8067969

Claim:
An integrated circuit, comprising: a pull-up compensation path unit comprising a transistor receiving an input signal at its gate, and configured to adjust a pull-up driving power of the input signal to compensate for an abnormal pull-up operation; a pull-down compensation path unit comprising a transistor receiving the input signal at its gate, and configured to adjust a pull-down driving power of the input signal to compensate for an abnormal pull-down operation; and a path control unit configured to route the input signal to one of the pull-up compensation path unit and the pull-down compensation path unit, wherein the path control unit includes: a control unit configured to generate a control signal in response to an operation mode signal and a supply voltage; and a selection unit configured to provide the input signal to one of the pull-up compensation path unit and the pull-down compensation path unit in response to the control signal.
