    摘要: A semiconductor memory includes a ferroelectric capacitor having a ferroelectric film, a first electrode formed on the ferroelectric film and a second electrode formed under the ferroelectric film. A data writing unit causes a first state in which the ferroelectric film has polarization in a direction from the first electrode to the second electrode or in a direction from the second electrode to the first electrode and has a substantially saturated polarization value or a second state in which the ferroelectric film has polarization in the same direction as in the first state and has a substantially zero polarization value, thereby writing a data corresponding to the first state or the second state in the ferroelectric capacitor. A data reading unit detects whether the ferroelectric capacitor is in the first state or in the second state, thereby reading a data stored in the ferroelectric capacitor.

    摘要: In the present invention, a polarization having a lower polarization level than a saturation polarization is caused in a ferroelectric capacitor by applying a voltage that is lower than a saturation voltage to the ferroelectric capacitor. This allows a storage device to store many values by changing a length of a write-time during which the voltage is applied to the capacitor.
