PROBLEM TO BE SOLVED: To provide a data output circuit and a control method of a semiconductor memory apparatus, of which the data output period is made to be reduced by reducing a layout area to simplify a circuit design. SOLUTION: The data output circuit includes: a plurality of pads in which the pad to be used exclusively or used commonly is determined for at least two or more kinds of unit data output modes; a plurality of data lines for transmitting data from memory banks to the outside of the memory banks; an output control means for output data from the data line according to at least one control signal among the plurality of data lines, to a signal line corresponding to the pad to be used in a currently set unit data output mode among the plurality of pads.
