Mass production of the first 50nm 256M NOR Flash in China, a new era of 50nm technology is fully opened


The 50nm 256M ETOX NOR Flash developed by Boya Technology was successfully taped out in Shanghai Huali in early 2020 and has now been successfully mass-produced. This product is the first 50nm 256M NOR Flash in China. Compared with similar products of international first-line brands, the product performance parameters have reached the same level or even higher. Its successful mass production marks the official entry of domestic NOR Flash high-capacity products into the 50nm era.

Dr. Li Di, CEO of Boya Technology, said: “The successful mass production of 50nm NOR Flash has greatly improved the international competitiveness of China’s memory chips from the market supply side and helped the country’s new economic construction. It can better meet the needs of communications, Internet of Things, The development needs of new infrastructure fields such as the Industrial Internet provide strong support for the strengthening and optimization of the real economy. Boya Technology is the only NOR Flash supplier in the world that has both the ETOX process and the SONOS process. Through the cooperation with Shanghai Huali, it can achieve continuous Innovation."

  Dr. Shao Hua, Vice President of Shanghai Huali R&D, said: "The latest cooperation between Shanghai Huali and Boya Technology has verified the continuous breakthroughs in chip design and process technology. The 50nm 256M NOR Flash has a higher density than the mainstream 65nm NOR Flash process in the industry. The integration and smaller Die size have further enhanced competitiveness in terms of product performance and cost. We are very happy to work with Boya Technology to expand the NOR Flash product line to meet the wide range of applications of its end customers."
