CoinWorld news: U.S. Commerce Secretary Lutnick urged Samsung Electronics and SK Hynix to ramp up memory chip production expansion in the United States to help ease the global shortage of key components for AI development. Lutnick confirmed that he is in talks with the two South Korean memory chip manufacturers, but did not disclose specifics. He acknowledged that Micron CEO Mehrotra may not welcome competitors expanding their presence in the U.S., but Lutnick said this move is necessary to make the U.S. chip supply chain more resilient.
