Abstract
A semiconductor device includes an output control circuit configured to generate a pre-output control signal and an output control signal according to the number of times that an output strobe pulse is inputted. The semiconductor device also includes a pipe circuit configured to generate latched data by latching input data on the basis of an input control signal, select some bits of the bits of the latched data and set the selected bits to pre-output data on the basis of the pre-output control signal, and output the pre-output data as output data on the basis of the output control signal.
