ABSTRACT:
A semiconductor device for providing a reliable data valid window includes a drive control unit configured to output a driving power control signal in response to an internal clock and a command signal; a sub-drive voltage supply unit configured to supply sub-drive voltages; a main drive unit configured to generate a delay-locked loop (DLL) clock by driving the internal clock with a main drive voltage; a sub-drive unit configured to drive the internal clock with the sub-drive voltage in response to the driving power control signal; and a data output driver configured to drive and output a data signal in sync with the DLL clock, wherein the main drive unit and the sub-drive unit share their output terminal.
