Abstract: In a memory cell including a ferroelectric capacitor, data is read without data destruction. When the reading operation is performed in the memory cell including the ferroelectric capacitor, voltage applied to the counter electrode of the ferroelectric capacitor is gradually increased so as not to cause polarization destruction in the ferroelectric capacitor. A first reading operation from the memory cell is performed by applying a first voltage that does not cause polarization inversion of the ferroelectric layer to the capacitor, a second reading operation from the memory cell is performed by applying a second voltage that does not cause polarization inversion of the ferroelectric layer to the capacitor, and the second voltage is higher than the first voltage.

Abstract: An oscillator capable of quick startup is provided. A transistor is provided between an output terminal of a certain stage inverter and an input terminal of the following stage inverter included in the voltage controlled oscillator. With the use of the on resistance of the transistor, the oscillation frequency of the clock signal is controlled. While supply of the power supply voltage is stopped, a signal that is input to the input terminal of the inverter just before supply of the power supply voltage is stopped is stored by turning off the transistor. This operation makes it possible to immediately output a clock signal that has the same frequency as that before supply of the power supply voltage is stopped at the time when the power supply voltage is supplied again.
