Chinese Researchers Achieve 10 Billion Write Cycles in Wurtzite Ferroelectric Memory

A team of researchers from Xidian University in Xian, along with City University of Hong Kong and Fudan University, has made a significant breakthrough by demonstrating over 10 billion writing cycles in wurtzite ferroelectrics. This achievement, reported in the journal Science on Thursday and highlighted by Xian Daily on Saturday, surpasses previous endurance records by nearly 100 times. This development tackles a major issue in the reliability of ferroelectric memory, which is being explored for future high-performance computing and AI storage solutions, driven by the growing need for advanced semiconductors. Wurtzite ferroelectrics, such as aluminium scandium nitride (AlScN), are known for their fast switching and low energy consumption, making them ideal for upcoming memory devices. Earlier, AlScN devices only managed about 100 million writing cycles, but this new research improves durability by controlling nitrogen-vacancy movement.
