Semiconductor apparatus and semiconductor system

摘要

Provided is a semiconductor apparatus including a plurality of semiconductor chips coupled through an electrical coupling unit. Each of the semiconductor chips includes: a chip ID signal generation unit configured to generate a chip ID signal; and a chip enable signal generation unit configured to receive a clock enable signal in response to the chip ID signal, wherein one of the semiconductor chips shares the received clock enable signal as a transfer clock enable signal with the other semiconductor chips, and the chip enable signal generation unit detects whether or not an error occurs in the chip ID signals of the plurality of semiconductor chips, selects any one of the transfer clock enable signal and the clock enable signal applied, and outputs the selected signal as a chip enable signal.
