Latest Patents
Hagiwara holds a patent for a ferroelectric memory and its operating method. This nonvolatile decision memory unit is designed to store decision data that indicates whether the data in normal memory cells is true or false. The invention includes an inversion control circuit that sets the inverting signal to a valid level with a predetermined probability. A write circuit is responsible for writing data that has logic inverse to the data being rewritten in the normal memory cells. This process also involves writing decision data indicating false to the decision memory unit when the inverting signal is valid. By rewriting inverse data at a predetermined frequency, the invention prevents imprinting during repetitive read operations. Additionally, it minimizes the deterioration of the ferroelectric capacitor by preventing frequent reverse polarization due to rewrite operations. This innovation significantly improves the reliability of ferroelectric memory systems.
