ABSTRACT:
A semiconductor memory device includes: a modulation controller for generating a modulation control signal for controlling a frequency modulation operation; a delay locked loop (DLL) circuit for performing a delay locking operation to generate first and second DLL clocks and outputting a frequency-modulated DLL clock in response to the modulation control signal; and a data strobe signal generator for outputting the frequency-modulated DLL clock as a data strobe signal.
