Title: Kenichi Hidaka: Innovator in OTP Memory Technology
Introduction
Kenichi Hidaka is a prominent inventor based in Kanagawa, Japan. He has made significant contributions to the field of memory technology, particularly in the development of one-time programmable (OTP) memory systems. With a total of 11 patents to his name, Hidaka's work has advanced the capabilities and confidentiality of memory storage solutions.
Latest Patents
One of Hidaka's latest patents focuses on enhancing the confidentiality of OTP memory. The invention describes a memory cell that includes a memory transistor, which forms a current path between first and second nodes, and a selection transistor that creates a current path between third and fourth nodes. The third node is connected to the gate of the memory transistor via a line, while a capacitor is coupled to the first node. By applying a high voltage that does not break but deteriorates the gate oxide film, the gate leak current in the memory transistor is increased, allowing data to be written. The data can then be read based on the presence or absence of charge leaks accumulated in the capacitor. This innovative approach ensures that the position of deterioration in the gate oxide film cannot be easily identified through physical analysis, thereby enhancing confidentiality.
