Abstract
A semiconductor device includes a flag shifting circuit and an auto-pre-charge control circuit. The flag shifting circuit generates a first shifted flag signal by shifting a first flag signal by a second latency period, the first flag signal generated based on a first operation clock signal, and configured to generate a second shifted flag signal by shifting a second flag signal by a first latency period, the second flag signal generated based on a second operation clock signal. The auto-pre-charge control circuit generates an auto-pre-charge signal by shifting the first shifted flag signal and the second shifted flag signal by a recovery period based on the first operation clock signal and the second operation clock signal.
