Abstract: The on-chip data transmission controller comprises a data comparison unit for comparing current data with previous data and issuing an inversion flag if the number of data bits phase-transited is larger than a preset number, a first data inversion unit for inverting a phase of the current data when the inversion flag is activated and providing inverted data onto a data bus, and a second data inversion unit for inverting a phase of the data transmitted via the data bus when the inversion flag is activated and outputting inverted data.

Abstract: A DLL with a reduced size, a semiconductor memory device including the DLL and a locking operation method of the DLL that includes a phase detector, a delay line, a delay controller, a delay circuit and an output buffer. The phase detector detects phase difference between input clock signals and feedback clock signals, and outputs phase detection signals according to results of the detection. The delay circuit delays reference clock signals during predetermined time and outputs the delayed signals as feedback clock signals. The output buffer outputs internal clock signals in response to delay clock signals. The reference clock signals are generated by one of circuits that exist in an actual output path of the internal clock signals. Accordingly, it is possible to reduce skew between the data strobe signals/the output data signals and the external clock signals, which may occur according to conditions in manufacturing processes, and to reduce the occupation area of the DLL.

Abstract: A memory device minimizes the skew between an external clock and a DQS (or DQ) after the locking state by regulating a delay ratio of a replica delay model to compensate errors of process, temperature or voltage change.

Here, the DLL comprises a replica delay model for modeling delay factors of the input clock buffer and other delay factors until the output clock outputted from the delay line is outputted to the outside of a chip, and for regulating a delay ratio in response to a plurality of control signals inputted externally in a test mode.
