Abstract
A semiconductor device with an interface includes a master device and a plurality of slave devices. The master device includes a master interface. The slave devices are stacked on the master device one after one as a three-dimension (3D) stack. Each of the slave devices includes a slave interface and a managing circuit, the master interface and the slave interfaces form the interface for passing signals in communication between the master device and the slave devices. The managing circuit of a current one of the slave devices drives a next one of the slave devices. An operation command received at the current one of the slave devices is just passed to the next one of the slave devices through the interface. A response from the current one of the slave devices is passed back to the master device through the interface.
