Abstract:
1. An integrated circuit device including a first input pin through which a signal is applied to a first internal circuit and a second input pin through which a signal is applied to a second internal circuit, the integrated circuit device comprising: a distribution unit which receives and outputs a first input signal input via the first input pin, and receives and outputs a second input signal input via the first input pin in response to a control signal; a level fixing unit which receives the first input signal from the distribution unit and applies a signal having the same voltage level as the first input signal to a first internal circuit in response to the control signal; and an activation unit which receives the second input signal input via the second input pin and applies the second input signal to a second internal circuit or applies the second input signal output from the distribution unit to the second internal circuit in response to the control signal.
