Abstract
A semiconductor memory device includes a memory region from which first data and second data are sequentially read, and a data output circuit suitable for selectively performing a reset operation on a data pad according to a logical relationship between the first and second data during an output disable period between a first output enable period corresponding to first output data and a second output enable period corresponding to second output data, when sequentially outputting the first and second output data corresponding to the first and second data through the data pad.
