A computer-implemented method is described. Each of the plurality of electric products is structured to be capable of outputting a first power request signal for requesting a desired amount of power. An erased cell in the present invention is a cell in the \u201coff\u201d state. The method first designates a starting block where buffering starts and searches for the starting block in the blocks. The second pulse generation circuit, operable in the destination clock domain, is configured to generate a destination data pulse from the sampled source data pulse.
