Abstract
A semiconductor memory device includes: an enable signal generation portion suitable for generating a data output enable signal activated at a predetermined first moment corresponding to column address strobe (CAS) latency based on a read command, a strobe signal generation portion suitable for generating a data strobe signal which has a preamble section until the data output enable signal is activated from a predetermined second moment ahead of the first moment based on the read command and toggles based on a source clock during an activated section of the data output enable signal, and a data output portion suitable for outputting internal data in synchronization with the data strobe signal during the activated section of the data output enable signal.
