1. A semiconductor device comprising:
an input/output circuit electrically connected to an external controller, wherein the input/output circuit includes: a first circuit configured to electrically connect one of first data bus input one of first and second data and second data bus input a third data with a third data bus, and electrically connect the one of first signal line input a first clock signal and second signal line input a second clock signal with a third signal line; a second circuit configured to output one of first to third data, which are input from the third data bus, in a first-in-first-out (FIFO) format; and a third circuit configured to generate the first clock signal and supply the first clock signal to the first circuit through the first signal line, when the one of the first and second data is read, the second circuit receives the one of the first and second data in response to the first clock signal within a period until a first signal is received after a read command and address data are received from the external controller, and when the third data is read, the second circuit receives the third data in response to the second clock signal within the period. |
