1. A data input/output device comprising:
a control circuit configured to:
generate a plurality input control signals in synchronization with a write clock,
perform a domain crossing operation of converting a write clock into a read clock, and
generate a plurality of output control signals based on an output counting signal generated through the domain crossing operation; and
a data input/output circuit configured to:
latch, in synchronization with the plurality of input control signals, a plurality of pieces of internal data input in parallel, and
serialize, in synchronization with the plurality of output control signals, the latched plurality pieces of internal data to generate data.
