Abstract
A semiconductor device comprises: a control signal generating circuit that generates and outputs a control signal that is in an active state during a period around at least one of rising edges and falling edges of a clock signal; and a data input circuit that is controlled to be in an active state, in which a data signal can be received, while the control signal is in an active state, and otherwise controlled to be in an inactive state.
