Abstract
A semiconductor device includes a master chip and a first slave chip. The master chip outputs a write signal or read signal and a chip identification (ID) signal and outputs data through a transmitter activated by the write signal or receives data through a receiver activated by the read signal. The first slave chip enters a write operation according to the write signal and activates a first receiver to store the data when the chip ID signal has a first logic level combination. The first slave chip enters a read operation according to the read signal and configured to activate a first transmitter to output the data when the chip ID signal has a first logic level combination. The master chip and the first slave chip are vertically stacked and are electrically connected to each other by a plurality of through electrodes penetrating the first slave chip.
