Latest Patents

One of Kaneko's latest patents is 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 the inverse logic of the data to be rewritten in the normal memory cells. This process also involves writing decision data indicating false to the decision memory unit when the inverting signal indicates a valid level. 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.

Another notable patent is for a contactless apparatus and card-type device featuring a clock rectifier that operates independently of the power rectifier and demodulator. This information processing apparatus receives a carrier wave modulated with information and extracts both the information and power to execute specific processes. The design allows for a demodulation circuit that is structurally independent of the dc power generating circuit, eliminating interference between the elements and enabling simpler designs. This optimal design also reduces power consumption in the apparatus.
