Abstract
A semiconductor device includes a plurality of chips, at least one line, and a controller. Each of the chips includes a chip input/output (I/O) pad, a transceiver configured to perform a transmission operation in response to a transmission enable signal or perform a reception operation in response to a reception enable signal, and a switch configured to couple the chip input/output (I/O) pad to the transceiver in response to a switch enable signal. The at least one line is configured to couple the chip input/output (I/O) pads contained in the plurality of chips. The controller generates the transmission enable signal, the reception enable signal, and the switch enable signal in response to a command signal and a chip identifier (ID) signal.
