SEMICONDUCTOR DEVICES AND SEMICONDUCTOR SYSTEMS INCLUDING THE SAME

摘要

A semiconductor system includes a controller and a semiconductor device. The controller outputs offset signals whose level combination is controlled according to temperature code signals including information on an internal temperature. The semiconductor device generates the temperature code signals according to a level combination of the offset signals. Further, the semiconductor device controls a refresh cycle time determined by the level combination of the offset signals.
