Abstract

An integrated circuit having a first circuit unit, which is put into a power-saving mode by a control apparatus and into a predetermined initial state when changing from the power-saving mode to a regular operating state. A second circuit unit is put into a power-saving mode by the control apparatus, during which the second circuit unit buffer-stores data and/or instructions adopted immediately prior to the power-saving state, with the second circuit unit resuming and providing the data and/or instructions when changing from the power-saving mode to the regular operating state. The second circuit unit has an input connection to which a first potential is applied in order to change to the power-saving mode and during the power-saving mode, and to which a second potential is applied in order to change to the operating state and during the operating state.
