Latest Patents: Hwa-Pyong Kim holds a patent for a delay-locked loop circuit, semiconductor memory device, and methods of operating a delay-locked loop circuit. This patent describes a delay-locked loop circuit that includes first and second duty cycle correctors, as well as first and second duty cycle detectors. The first duty cycle corrector adjusts the duties of some of the first through fourth divided clock signals to provide first through fourth corrected clock signals, in response to a first correction code. The second duty cycle corrector adjusts the delays of some of the second through fourth delayed clock signals to provide first through fourth source clock signals, in response to a second correction code. The first duty cycle detector detects the duty of the first propagation clock signal to generate a first sub-correction code of the first correction code, and the duties of the first and second recovered clock signals to generate the second correction code. The second duty cycle detector detects the duty of the second propagation clock signal to generate a second sub-correction code of the first correction code.
