Micron Technology, a leading memory-chip manufacturer, has announced a $3.6 billion investment in advanced memory chip production in Japan. The Japanese government will support the investment and will see Micron producing cutting-edge memory chips starting in 2025. The deal comes amid growing tensions between the United States and China over chip technology, with the U.S. imposing restrictions to slow down China's semiconductor advancement. Micron has faced geopolitical challenges, including a cybersecurity review in China that could lead to its expulsion from that market.
