Abstract: A data output device includes: a plurality of storage devices coupled in parallel to store input data, and having a storage region with a predetermined depth; and a selector suitable for selecting an output of any one storage device among the plurality of storage devices.

Abstract: A data output device includes: a first serializer suitable for receiving first parallel data having a first size from a first data line, and selectively outputting first and second serial data each having a second size corresponding to ½ of the first size; a second serializer suitable for receiving second parallel data having the first size from a second data line, and selectively outputting third and fourth serial data each having the second size; and a latch circuit suitable for latching the output of the first serializer and the output of the second serializer, and outputting serial output data having the first size.

Abstract: A semiconductor device includes: a power-gated logic circuit suitable for operating in response to a first power gating enable signal which is deactivated in a standby mode and activated in an active mode; a transmission unit suitable for selectively transmitting an output signal of the power-gated logic circuit to an output terminal in response to a third power gating enable signal; a clocked latch unit suitable for latching a signal of the output terminal in the standby mode and an initial stage of the active mode in response to a second power gating enable signal; and an internal circuit suitable for operating based on the signal of the output terminal, wherein the first to third power gating enable signals are sequentially activated.
