Abstract: Spread spectrum clock generators and electronic devices including the same are provided. An electronic device may include a memory and a first circuit block configured to output a first spread spectrum clock signal and a first address for accessing the memory. The electronic device may include a second circuit block configured to operate in response to a second spread spectrum clock signal, and configured to output a second address for accessing the memory. The electronic device may include a spread spectrum clock signal generator configured to receive the first spread spectrum clock signal to generate the second spread spectrum clock signal. The memory may be configured to compare the first and second addresses to each other to output a clock generator control signal corresponding to a difference between the first and second addresses.

Abstract: An ice maker, a refrigerator including the ice maker, and an ice making method are provided. The ice maker includes a tray having a predetermined length and to which water is supplied to make ice. The ice maker is configured to mechanically separate the ice from the tray by using pistons which are driven by being pressed by structures. This allows the ice maker to have a reduced size, and a small occupation area, thereby implementing a slim configuration of a refrigerator. Furthermore, since an installation height of the ice maker is lowered, a path for supplying cool air may be shortened. This may prevent loss of cool air being supplied to the ice making chamber. Since the ice maker has a simplified configuration and precise operation controls, the fabrication costs may be reduced, and inferiority of the ice maker due to malfunctions may be prevented.

Abstract: A phase interpolation circuit includes a waveform shaping unit and a phase interpolator. The waveform shaping unit adaptively waveform-shapes first or second phase offset input clock signal pair that is applied, to output first and second buffered clock signals having a rising time and falling time each of more than about a quarter of a period of the first and second offset input clock signals. The phase interpolator is applied to generate a phase interpolation clock signal selected from phases between the first and second buffered clock signals in response to a weight value of a phase interpolation control signal.
