|Title||Memory circuit provided with bistable circuit and non-volatile element|
A memory circuit is provided with: a bistable circuit for memorizing data; non-volatile elements in which the data memorized in the bistable circuit is stored in a non-volatile manner, and that restores the data stored in non-volatile manner in the bistable circuit; and a control unit.
When a period in which no reading or writing of data from the bistable circuit takes place is longer than a predetermined period, the control unit stores the data memorized in the bistable circuit in a non-volatile manner, and shuts down power supply to the bistable circuit.
When the period in which no reading or writing of data takes place is shorter than the predetermined period, the control unit makes a power supply voltage to the bistable circuit lower than a voltage for a period in which reading or writing of data from the bistable circuit takes place, without performing the non-volatile storing of the data memorized in the bistable circuit.
