    摘要: In a ferroelectric capacitor, two displacements (points b and c) of a remanent polarization correspond to data “1” and one displacement (point a) of the remanent polarization corresponds to data “0”. When the data “1” is written, either of two electric voltage pulses different in potential or in pulse width is applied to the ferroelectric capacitor to position the displacement of the remanent polarization in the ferroelectric capacitor at the point b or at the point c. When the data “0” is written, on the other hand, the displacement of the remanent polarization in the ferroelectric capacitor is positioned at the point a.

    摘要: A semiconductor memory device has a plurality of memory cells each having a first ferroelectric capacitor for storing data as a polarization value. First voltage applying means applies a first read voltage between the pair of electrodes of the first ferroelectric capacitor composing that one of the plurality of memory cells from which data is to be read. Data reading means detects the polarization value in the first ferroelectric capacitor when the first read voltage is applied between the pair of electrodes of the first ferroelectric capacitor and thereby reads the data stored in the first ferroelectric capacitor therefrom. A hysteresis loop in the first ferroelectric capacitor is shifted in a direction of voltage opposite in polarity to the first read voltage.

    摘要: A multi-valued data is written in a ferroelectric capacitor, which stores a multi-valued data in accordance with displacement of polarization of a ferroelectric film thereof, by applying a relatively high first writing voltage or a relatively low second writing voltage between a first electrode and a second electrode of the ferroelectric capacitor. Next, a potential difference induced between the first and second electrodes is removed. Then, the multi-valued data is read by detecting the displacement of the polarization of the ferroelectric film by applying a reading voltage between the second electrode and a substrate where a reading FET for detecting the displacement of the polarization of the ferroelectric film is formed. The reading voltage has the same polarity as the first writing voltage and is set to such magnitude that, in applying the reading voltage, a first potential difference induced between the gate electrode of the reading FET and the substrate when the multi-valued data is written by applying the first writing voltage is smaller than a second potential difference induced between the gate electrode and the substrate when the multi-valued data is written by applying the second writing voltage.
