Abstract
A semiconductor integrated circuit has a reception circuit configured to receive a strobe signal of which a logic is intermittently switched in synchronization with a data signal, an output circuit configured to extract a low frequency component including at least a DC component of the strobe signal received by the reception circuit and to output a first signal, and a comparison circuit configured to compare a signal level of the first signal with a threshold level. The reception circuit is configured to change a boost amount of a high frequency component different from the low frequency component of the strobe signal based on a comparison result obtained by the comparison circuit.
