1. An interface for a semiconductor device, the semiconductor device including a master device and a plurality of slave devices, wherein the master device and the slave devices are stacked up with electric connection, the interface comprising:
a master interface, implemented in the master device and including a master interface circuit with a master bond pattern;
a slave interface, implemented in each of the slave devices and including a slave interface circuit with a slave bond pattern to correspondingly connect to the master bond pattern; and
a clock route, to transmit a clock signal through the master interface and the slave interface,
wherein the master device transmits a command and a selecting slave identification through the master interface to all the slave interfaces;
wherein one of the slave devices corresponding to the selecting slave identification executes the command and responds a result back to the master device through the slave interfaces and the master interface.
