A circuit including a ferroelectric capacitor can be used to store the value of nodes of volatile logic elements in a logic circuit. In this manner, the state of a complex logic circuit, such as a CPU or an I/O device, can be stored in the non-volatile ferroelectric capacitors. After an accidental or planned power outage, the non-volatile ferroelectric capacitors can be used to restore the values of the nodes. Additionally, a planned power loss can be save system power in circuits that are power consumption sensitive.
