A method for reducing power consumption, and a system having power reduction capabilities, the method includes: storing, at a first circuit, data representative of a state of a second circuit, entering a low power mode, exiting low power mode, providing a default data value to the second circuit after exiting from the low power mode, and selectively providing data from the first circuit to the second circuit in response to the value of data and to a characteristic of a third circuit coupled to the first and second circuits. The system includes: a first circuit, a second circuit and a third circuit. The third circuit is connected between the first circuit and the second circuit. The first circuit is adapted to store data representative of a state of the second circuit. The first circuit is activated during a low power mode while the second circuit is deactivated during the low power mode. The second circuit is adapted to enter a default state after exiting from the low power mode. The third circuit selectively provides data from the first circuit to the second circuit in response to the value of the data and to a characteristic of a third circuit.
