A column control circuit may include a column control signal generation circuit and a column access block signal generation circuit. The column control signal generation circuit is configured to activate an input/output strobe signal when a column access block signal is deactivated. The column control signal generation circuit is configured to deactivate the input/output strobe signal when the column access block signal is activated. The column access block signal generation circuit is configured to activate the column access block signal when gap-less read commands may be inputted. The column access block signal generation circuit may deactivate the column access block signal during a period corresponding to an N-th read command among the gap-less read commands. N is an integer that is no less than 2.

Column control circuit and semiconductor device including the same

A semiconductor apparatus includes: a pad unit comprising a plurality of data input/output (I/O) pads and a plurality of error detection code pads; an error detection code (EDC) read path configured to generate a plurality of EDCs by performing an error detection operation on a plurality of data, and output the plurality of EDCs through the plurality of error detection code pads; a comparison circuit configured to generate a comparison result signal by comparing the plurality of EDCs; and a data read path configured to output the comparison result signal through any one of the plurality of data I/O pads.
