Chinese Scientists Achieve 100-Fold Leap in Memory Chip Durability
SCMP · 1 SOURCESabout 4 hours ago2 MIN
Summary
Chinese researchers have achieved a major breakthrough in semiconductor memory technology, developing a method to dramatically improve the durability of emerging ferroelectric memory chips. The team from Xidian University, collaborating with City University of Hong Kong and Fudan University, demonstrated that their wurtzite ferroelectric materials could endure more than 10 billion writing cycles — approximately 100 times the endurance previously achieved with the same material class. This development, published on Thursday in the journal Science, addresses a critical reliability barrier that has long hindered the commercial deployment of next-generation memory technology for artificial intelligence systems and high-performance computing applications.
Key Points
- Research led by Xidian University with City University of Hong Kong and Fudan University, published in Science on Thursday
- Achieved over 10 billion writing cycles in wurtzite ferroelectrics (AlScN), roughly 100 times the previous record of 100 million cycles
- Breakthrough overcomes nitrogen vacancy accumulation that previously caused material deterioration after repeated electrical switching
- AlScN materials offer rapid switching speeds, low energy consumption, and compatibility with existing semiconductor manufacturing processes
- Wang Ruiqing from Xidian University explained the mechanism by comparing ferroelectric material to a neatly planted cornfield with missing seedlings
Why It Matters
This breakthrough could accelerate the commercialization of ferroelectric random-access memory (FeRAM), potentially replacing or supplementing existing memory technologies in data centres and AI hardware. For Hong Kong's growing semiconductor research sector, the City University of Hong Kong's involvement signals emerging opportunities for local researchers to contribute to next-generation computing infrastructure as global demand for advanced memory solutions intensifies .
