Naoki Banno

About

Naoki Banno is a leading figure in the development of next-generation, nonvolatile programmable logic devices, with a core focus on atom switches and resistive-change memory technologies. His research is pivotal in creating robust, high-performance field-programmable gate arrays (FPGAs) that can operate in extreme environments. Banno’s major contributions include the pioneering demonstration of the NanoBridge-based FPGA, which leverages a novel resistive-change switch integrated in the back end of line (BEOL). This work, cited 9 times, highlights the NanoBridge’s high on/off conductance ratio and weak temperature dependence, making it ideal for high-temperature applications. Further expanding this frontier, Banno developed a robust Cu atom switch featuring a thermally tolerant polymer-solid electrolyte (TT-PSE) capable of withstanding over 400°C. This innovation, cited 6 times, achieves standard Cu-BEOL compatibility by selectively eliminating weak hydrocarbon bindings in the PSE, resulting in exceptional thermal stability. Through these achievements, Banno is advancing the reliability and versatility of nonvolatile programmable logic, enabling FPGAs that endure harsh conditions without sacrificing performance—a critical step for aerospace, automotive, and industrial electronics.
