Micron, a US memory chipmaker, announced on Friday (Jun 16) that it was dedicated to China and will invest 4.3 billion yuan (US$603 million) in its chip packaging factory in the Chinese city of Xian over the next few years.

The company has been targeted by China's cyberspace regulator, which announced last month that the firm, the world's largest memory chipmaker, had failed a network security examination and that the agency would prohibit major infrastructure operators from purchasing from the company.

Micron made no mention of the review's decision in a statement released on WeChat on Friday.

"This investment demonstrates Micron's unwavering commitment to its China business and team," said CEO Sanjay Mehrotra.

According to the business, the investment will entail purchasing packaging equipment from a Xian-based subsidiary of Taiwan's Powertech Technology Inc, which Micron has been utilising in the production since 2016.

It will also establish a new production line at the facility to produce mobile DRAM, NAND, and SSD products in order to improve the plant's packaging and testing capabilities.
