Radiation Hardened Memristive Technologies for Space-based Nonvolatie Memory
Abstract
Arizona State University Grant #: FA9453-15-1-0080 “Radiation Hardened Memristive Technologies for Space-based Nonvolatie Memory” Abstract The goal of the proposed research is to determine and demonstrate the viability of resistive RAM (RRAM) as a viable non-volatile-memory NVM technology for space electronics and to optimize RRAM array architectures and peripheral circuitry for space applications. RRAM is regarded as one of the most promising candidates for non-volatile memory (NVM) applications beyond the scaling limit of FLASH. This research will further the development and transition of innovative high-payoff technologies supporting government and commercial spaceflight. The memory elements for RRAM are two terminal structures with resistance values set by voltage levels applied across device electrodes. RRAM devices are typically categorized into two classes, one anion-based and the other cation-based, both of which will be studied during this program. Preliminary studies have shown that when compared to the mainstream FLASH technology, the RRAM technology has much better total ionizing dose (TID) tolerance, better programming cycle endurance, faster programming speed, lower programming voltage requirements, and better scalability to sub 10 nm feature sizes, making RRAM a strong candidate for supplanting FLASH as the most widely used NVM technology. Given these advantages, the RRAM technology shows improved performance and radiation hardness as compared to FLASH technology, bringing significant benefits to the next generation of government and commercial space systems and industries developing robust non-volatile memory for space electronics. During the three year research effort Arizona State University will: acquire commercial parts and fabricate high density arrays of RRAM, characterize how parts and arrays respond to stress, perform cumulative radiation damage and heavy ion testing, develop and validate models, examine RRAM architectures to assess suitability for space, develop fabrication processes to enhance radiation tolerance, and design architectures using layout and radiation-hardening-by-design methodologies.
