Chinese memory semiconductor company CXMT has begun small-scale production of the high-bandwidth memory chip HBM3E, a critical component for artificial intelligence. [^1]

Google is accelerating its schedule for developing and rolling out its own customized chips. [^2]

The company is shifting from a two-year cycle for each generation to introducing two chips a year. [^3]

Rani Borkar, president of Azure Hardware Systems and Infrastructure at Microsoft, stated on September 2, 2026, that building massive new memory chip capacity will not resolve the supply chain bottlenecks holding back the AI infrastructure build-out. [^4]

Industry sources previously expected CXMT to begin mass production of HBM3 this year, but development speed accelerated to the next generation, HBM3E. [^5]

SK Hynix began HBM3E mass production in 2024, meaning the technology gap between South Korea and China is now approximately three years. [^6]

The goal of the accelerated schedule is to stay ahead in the artificial intelligence race. [^7]
