ABSTRACT:
A clamp circuit for clamping potential of an internal node electrically connected to an external terminal has its clamping function activated and inactivated selectively in accordance with a control signal generated by a control circuit in response to a forced monitor mode activating signal. An output portion of a substrate potential generating circuit generating a prescribed internal voltage is selectively connected to the internal node in response to a control signal generated from a second control circuit in response to the forced monitor mode activating signal. In a semiconductor device having the clamp circuit for absorbing surge current, pin contact test, external monitoring of an internal potential and external application of the internal potential can be realized.
