Abstract:
A semiconductor system includes a controller configured to output a clock enable signal, first to third command/address signals, a chip select signal, first and second entry commands and an exit command, and receive an output signal; and a semiconductor device configured to latch the first and second command/address signals and transfer the output signal in response to the chip select signal and the first entry command, latch the first and third command/address signals and transfer the output signal in response to the chip select signal and the second entry command, and transfer data generated by the first to third command/address signals as the output signal in response to the clock enable signal and the exit command signal.
