ABSTRACT:
The semiconductor integrated circuit comprises: a first buffer circuit that outputs a first output signal to an output terminal on receipt of a first input signal; a second buffer circuit that includes a circuit having a similar configuration to the first buffer circuit, that outputs a second output signal on receipt of the first input signal, and that outputs the second output signal based on a check signal; a third buffer circuit that outputs a third output signal based on the check signal; a determination circuit that receives the second output signal and the third output signal and activates a detection signal, in response to the detection that the second output signal is behind the third output signal; and a fourth buffer circuit that operates during the activation of the detection signal and outputs the third output signal to the output terminal, on receipt of the first input signal.
