Patent ID: 8120442

Claim:
A semiconductor device, comprising a plurality of transmission units, each including a transmission line to convey a signal, a transition detector to check whether a transmission signal on the transmission line is transited, and if so detect its transition shape, and a primary delay unit coupled to the transmission line to adjust a transmission delay of the transmission signal, the transmission lines of the transmission units being successively adjacent to each other; and respective signal mode determining units to determine signal transmission modes between pairs of adjacent transmission lines among the transmission lines of the plurality of transmission units, in response to output signals of the transition detectors, the primary delay units of the transmission units adjusting transmission delays of the transmission signals conveyed by the respective transmission lines depending on corresponding output signals of the signal mode determining units wherein each of the primary delay units includes a control signal generator for generating a delay control signal in response to a corresponding output signal from a respective one of the signal mode determining units, and a plurality of MOS capacitors, coupled to each of the plurality of transmission lines and being under the control of the corresponding delay control signal.
