U.S. Tightens China’s Access to A.I. Chips

The Biden administration on Tuesday announced additional limits on sales of advanced semiconductors by American firms, shoring up restrictions issued last October to limit China’s progress on supercomputing and artificial intelligence. The rules appear likely to halt most shipments of advanced semiconductors from the United States to Chinese data centers, which use them to produce models capable of artificial intelligence. More U.S. companies seeking to sell China advanced chips, or the machinery used to make them, will be required to notify the government of their plans, or obtain a special…

How the Big Chip Makers Are Pushing Back on Biden’s China Agenda

A year after the Biden administration took its first major step toward restricting the sale of semiconductors to China, it has begun drafting additional limits aimed at denying Beijing the technology critical to modern-day weapons. But in recent months, its progress has been slowed as American chip companies have pushed back with a blunt warning: Cutting sales to China would gut their businesses and derail the administration’s plan to build new semiconductor factories in the United States. Since July, Nvidia, Intel and Qualcomm, three of the world’s largest chip makers,…

Interest Rate Jitters Sink the Giants of Tech

Market whiplash In the span of a month, the bottom has dropped out of the bull-market rally as investors have come to grips with the prospect of “higher for longer” interest rates worldwide. The sell-off in global stocks and bonds picked up steam on Thursday. And weary market watchers will be looking for more hints on the Fed’s view at next week’s Jackson Hole summit of central bankers and policymakers. Technology stocks have been hit particularly hard. The high-flying FANG+ Index — which comprises the largest tech stocks by market…

The Chip Titan Whose Life’s Work Is at the Center of a Tech Cold War

In a wood-paneled office overlooking Taipei and the jungle-covered mountains that surround the Taiwanese capital, Morris Chang recently pulled out an old book stamped with technicolor patterns. It was titled “Introduction to VLSI Systems,” a graduate-level textbook describing the intricacies of computer chip design. Mr. Chang, 92, held it up with reverence. “I want to show you the date of this book, 1980,” he said. The timing was important, he added, as it was “the earliest piece” in a puzzle that came together for him — altering not only his…

Biden Administration Weighs Further Curbs on Sales of A.I. Chips to China

The Biden administration is weighing additional curbs on China’s ability to access critical technology, including restricting the sale of high-end chips used to power artificial intelligence, according to five people familiar with the deliberations. The curbs would clamp down on the sales to China of advanced chips made by companies like Nvidia and Advanced Micro Devices and Intel, which are needed for the data centers that power artificial intelligence. Biden officials have said that China’s artificial intelligence capabilities could pose a national security threat to the United States by enhancing…

White House Reportedly Weighs New A.I. Export Limits

Will the U.S. tighten a cordon around A.I. chips? Shares in high-flying chipmakers like Nvidia and AMD were down in premarket trading today, after The Wall Street Journal reported that the Biden administration is weighing new restrictions on exporting artificial intelligence-related semiconductors to China. The deliberations underscore the White House’s worries about falling behind in the race to dominate A.I. and the potential for Beijing to use the technology in military applications — and they show that it is willing to tighten the screws on trade to stay ahead. Any…

Chip Makers, Once in High Demand, Confront Sudden Challenges

A few months ago, makers of computer chips seemed on top of the world. Customers could not get enough of the small slices of silicon, which act as the brains of computers and are needed in just about every device with an on-off switch. Demand was so strong — and U.S. dependence on a foreign manufacturer so worrying — that Democrats and Republicans agreed in July on a $52 billion subsidy package that included grants to build new chip factories in America. U.S. chip makers such as Intel, Micron Technology,…

U.S. Said to Plan New Limits on China’s A.I. and Supercomputing Firms

The Biden administration has faced some criticism that it has moved slowly to curb China’s access to cutting-edge U.S. technology. For many administration officials, China’s recent progress in clearing a key technological hurdle in semiconductor manufacturing underscored the urgent need for more expansive regulation in the industry, people familiar with the discussions said. The export controls are part of a bigger strategy from the Biden administration to starve China of key technologies while pumping money into U.S. chip-making factories. The measures come as Beijing ramps up its aggression toward Taiwan,…
