China Bans US Memory Chipmaker Micron, Prompting Pushback

US Senate's top Democrat and Biden administration are working to address China's ban on sales of Micron Technology's memory chips.
China imposed restrictions against Micron, the biggest US memory chipmaker, as part of a widening US-China trade dispute.
The White House says China's ban on Micron is "not based in fact" and is troubling.
China defends the ban, accusing the US of "economic coercion," though the ban hampers China's chip industry.
Micron estimates the ban could reduce its revenue, though the White House says it won't torpedo US-China relations.
