Title: Polarization erasing method for ferroelectric memory
Inventor: ARITA MEI
IPC: G11C11/22
Filed: 2001-06-25
Abstract: PROBLEM TO BE SOLVED: To prevent imprint degradation by making the amount of polarization of a ferroelectric capacitor to be roughly zero. SOLUTION: First, '1' data are written in a ferroelectric capacitor. The polarizing characteristic of the capacitor is shifted to the position of P1 by stopping a voltage application to the capacitor after a prescribed voltage V0 is applied at both ends of the capacitor. Next, '0' data are written in the capacitor. The polarizing characteristic of the capacitor is shifted to the position of P5 by applying a reverse voltage -V0 to the capacitor for a preliminarily obtained polarization erasing time (Tth) and, thereafter, the polarizing characteristic of the capacitor is shifted to the position of P6 where polarization is '0' by stopping the application voltage.  As a result, it is made possible to make the polarization of the capacitor to be zero and thus it is made possible to prevent the imprint degradation even with respect to a high temperature treatment in the succeeding packaging process by performing such a polarization erasing processing after a probe inspection.
