Abstract

A semiconductor device may include first to fourth output lines, an input signal latch unit suitable for latching first to fourth input signals that are sequentially inputted in response to first to fourth clocks having sequential phases, respectively, a valid signal latch unit suitable for latching a valid signal in response to one clock among the first to fourth clocks, where the valid signal corresponds to one input signal among the first to fourth input signals and represents whether the corresponding input signal is valid or not, and a signal transfer unit suitable for transferring the latched input signals, which are obtained by latching the input signals in response to the first to fourth clocks, to the first to fourth output lines based on a correspondence relationship that is decided based on a valid signal latch result of the valid signal latch unit.

First claim

What is claimed is:

1. A semiconductor device, comprising:
first to fourth output lines;
an input signal latch unit suitable for latching first to fourth input signals that are sequentially inputted in response to first to fourth clocks having sequential phases, respectively;
a valid signal latch unit suitable for latching a valid signal in response to one clock among the first to fourth clocks, where the valid signal corresponds to one input signal among the first to fourth i…
