Summary: | A semiconductor memory device includes a delay locked loop (DLL) unit configured to generate a plurality of DLL clocks, each having a different phase according to delay values predefined by a DLL operation; a data output buffering unit configured to output data in response to the DLL clocks; and a skew compensating unit disposed between the DLL unit and the data output buffering unit to remove a clock skew occurring when the DLL clocks are transferred to the data output buffering unit. |
