The United States Commerce Department’s decision to impose a 25% national security tariff on certain high-end semiconductors is only the “phase one” s.

Chinese customs authorities told customs agents this week that Nvidia's H200 artificial intelligence chips are not permitted to enter China, according to three people briefed on the matter. Chinese government officials also summoned domestic technology companies to meetings on Tuesday where they were explicitly instructed not to purchase the chips unless necessary,

The agreement with the start-up Cerebras is the latest in a series intended to expand the A.I. company’s computing power.

At CES 2026, sleek new laptops dazzled—but soaring memory costs driven by AI chip demand threaten to make everyday PCs pricier and less powerful.

As the company explains it, the new Rubin line of chips are built to treat the AI data center as the "unit of compute," not just a single GPU server. The platform includes six chips that are built to work as one, with GPUs, CPUs, and other components co-designed to share data faster.

Flash memory cells work by using a large voltage to effectively ram electric charge across an insulated gap. Once there, it can remain stored for very long periods of time before requiring a top-up. Single-Level Cell (SLC) works like a switch: it either has all the charge or none, giving you two states or one bit of digital information.

SAN FRANCISCO, Jan 15 Reuters) - SiFive, which makes blueprints for parts of complex chips, said on Thursday it will become the first maker of RISC-V chip designs to integrate Nvidia technology that creates speedy links between chips.

Micron makes hardware components that are critical for AI data centers, and demand is exceeding supply, yet its stock is one of the best values in the space right now.
