The SIP semiconductor device includes chips including first and second chips. Each of the chips includes an alive block, a local interface, and an intellectual property (IP) block. The alive block is continuously supplied with power in order to continuously be in an on-state. The local interface transmits/receives data to/from other chips. The IP block individually stores and processes data. The alive blocks of the chips are connected to each other through a first signal line unit for transmitting a signal required to wake up or initialize the chips. The alive blocks control power to the chips, respectively, in response to an external wake-up instruction signal or the signal transmitted through the first signal line unit.
