PURPOSE: To use ferroelectric substance capacitors and a storage circuit section by constituting the data storage circuit which includes two ferroelectric substance capacitors connected in series and the electronic circuit that is connected to the common connection point of the capacitors to store data. CONSTITUTION: The circuit element is formed by coupling two ferroelectric substance capacitors. Capacitors 12 and 14 have an approximately equal physical structure and size. Three contacting points are obtained, i.e., two outer points 18 and 20 which are called 'electrodes' and a common connecting point 16 located between the capacitors. The point 16 is electrically connected to both capacitors 12 and 14. On the other hand, the electrodes 18 and 20 are connected to respective one capacitor. The circuit is named as a programmable capacity divider 10. Then, the voltage, which indicates the former polarization of the ferroelectric substance material in the divider 10, is generated at the point 16. Thus, the ferroelectric substance capacitor array is used as the capacity divider which is useful in the applications for storage devices and others. |
