Abstract
A semiconductor system includes a first semiconductor device and a second semiconductor device. The first semiconductor device outputs first to (M+1)command/address signals (wherein, 'M' denotes a natural number which is equal to or greater than two) and receives a detection signal to detect a normality/abnormality of a temperature sensor. The second semiconductor device enters a test mode in response to the (M+1)command/address signal and compare first to Nsensing codes (wherein, 'N' denotes a natural number which is equal to or greater than two) generated by the temperature sensor with the first to Mcommand/address signals to generate the detection signal. The second semiconductor device also executes a refresh operation in response to a refresh signal including a plurality of pulses whose cycle time is controlled by the first to Mcommand/address signals.
