Abstract
An output detection and pulse generation circuit is disclosed. The output detection and pulse generation circuit includes a comparison circuit configured to receive first data to be transmitted to a logic circuit according to a first clock signal and generate a comparison signal by comparing the first data with second data transmitted to the logic circuit in a first phase, and a control signal generation circuit configured to output the comparison signal generated in the first phase as a control signal for controlling activation or deactivation of the logic circuit according to a second clock signal in a second phase.
Claims19
