Abstract:
A data strobe clock buffer of a semiconductor memory apparatus includes a buffering block configured to buffer an external data strobe clock signal in response to a buffer enable signal to generate an internal data strobe clock signal, a timing discriminating block configured to discriminate toggle timing of the internal data strobe clock signal in response to a burst start signal and a burst length signal to generate a timing discrimination signal, and an enable controlling block configured to generate the buffer enable signal in response to the timing discrimination signal.
