Abstract:
A semiconductor system may include a controller and a semiconductor device. The controller may output command/address signals. The semiconductor device may generate a plurality of control codes from the command/address signals in a test mode according to a combination of the command/address signals. The semiconductor device may output a first output datum generated by serializing the plurality of control codes, and the first output datum, through a single pad.
