Abstract
A semiconductor device includes a sampling code generation circuit and a code comparator. The sampling code generation circuit includes a buffer circuit configured to receive an external set signal. The sampling code generation circuit is configured to perform a count operation during a sampling period, the sampling period adjusted based on an output signal of the buffer circuit to generate a sampling code. The code comparator is configured to compare the sampling code with a reference code to generate a comparison flag.
