Abstract
A semiconductor system includes a controller and a semiconductor device. The controller outputs a burn-in test signal, a clock signal and command/address signals. The semiconductor device enters a first test mode if the burn-in test signal is inputted. The semiconductor device enters a second test mode according to a level combination of the command/address signals in synchronization with the clock signal after the semiconductor device enters the first test mode. The semiconductor device enters a third test mode according to an other level combination of the command/address signals in synchronization with the clock signal after the semiconductor device enters the second test mode.
