Abstract
A semiconductor system includes a controller and a semiconductor device. The controller outputs an external command signal. The semiconductor device compares the external command signal with a reference voltage signal to generate a refresh signal. The semiconductor device executes a refresh operation according to the refresh signal. The refresh signal is enabled if the reference voltage signal is not generated.
