A team from the University of Southern California has developed a new type of memory chip featuring a 'sandwich' structure with memristors as its core components. This chip can operate stably at high temperatures of 700°C without performance degradation, preventing short circuits caused by metal atom migration. Experiments show that it can retain data for over 50 hours at 700°C without refreshing, withstand over 1 billion switching operations, and operate at nanosecond speeds with just 1.5 volts. The chip has broad application prospects, suitable for operations in extreme environments, and can also enhance the computational efficiency of AI systems while reducing energy consumption.
