Abstract
A semiconductor system includes a controller and a semiconductor device. The controller outputs pre-order address signals, post-order address signals, and an update signal including pulses periodically generated. The semiconductor device generates internal address signals counted by a predetermined number of times according to a combination of the pre-order address signals and a combination of the post-order address signals in response to a pulse of the update signal. The semiconductor device also performs a refresh operation according to a combination of the internal address signals.
