AI memory is sold out, causing an unprecedented surge in prices

All computing devices require a part called memory, or RAM, for short-term data storage, but this year, there won’t be enough of these essential components to meet worldwide demand.

That’s because companies like Nvidia, Advanced Micro Devices and Google need so much RAM for their artificial intelligence chips, and those companies are the first ones in line for the components.

Three primary memory vendors — Micron, SK Hynix and Samsung Electronics — make up nearly the entire RAM market, and their businesses are benefitting from the surge in demand.

″We have seen a very sharp, significant surge in demand for memory, and it has far outpaced our ability to supply that memory and, in our estimation, the supply capability of the whole memory industry,” Micron business chief Sumit Sadana told CNBC this week at the CES trade show in Las Vegas.

Micron’s stock is up 247% over the past year year, and the company reported that net income nearly tripled in the most recent quarter. Samsung this week said that it expects its December quarter operating profit to nearly triple as well. Meanwhile, SK Hynix is considering a U.S. listing as its stock price in South Korea surges, and in October, the company said it had secured demand for its entire 2026 RAM production capacity.

Now, prices for memory are rising.

TrendForce, a Taipei-based researcher that closely covers the memory market, this week said it expects average DRAM memory prices to rise between 50% and 55% this quarter versus the fourth quarter of 2025. TrendForce analyst Tom Hsu told CNBC that type of increase for memory prices was “unprecedented.”

Three-to-one basis

Chipmakers like Nvidia surround the part of the chip that does the computation — the graphics processing unit, or GPU — with several blocks of a fast, specialized component called high-bandwidth memory, or HBM, Sadana said. HBM is often visible when chipmakers hold up their new chips. Micron supplies memory to both Nvidia and AMD, the two leading GPU makers.

Nvidia’s Rubin GPU, which recently entered production, comes with up to 288 gigabytes of next-generation HBM4 memory per chip. HBM is installed in eight visible blocks above and below the processor, and that GPU will be sold as part of single server rack called NVL72, which fittingly combines 72 of those GPUs into a single system. By comparison, smartphones typically come with 8 or 12GB of lower-powered DDR memory.

But the HBM memory that AI chips need is much more demanding than the RAM used for consumers’ laptops and smartphones. HBM is designed for high-bandwidth specifications required by AI chips, and it’s produced in a complicated process where Micron stacks 12 to 16 layers of memory on a single chip, turning it into a “cube.”

When Micron makes one bit of HBM memory, it has to forgo making three bits of more conventional memory for other devices.

“As we increase HBM supply, it leaves less memory left over for the non-HBM portion of the market, because of this three-to-one basis,” Sadana said.

Hsu, the TrendForce analyst, said that memory makers are favoring server and HBM applications over other clients because there’s higher potential for growth in demand in that business and cloud service providers are less price-sensitive.

In December, Micron said it would discontinue a part of its business that aimed to provide memory for consumer PC builders so the company could save supply for AI chips and servers.

Some inside the tech industry are marveling at how much and how quickly the price of RAM for consumers has increased.

Dean Beeler, co-founder and tech chief at Juice Labs, said that a few months ago, he loaded up his computer with 256GB of RAM, the maximum amount that current consumer motherboards support. That cost him about $300 at the time.

“Who knew that would end up being ~$3,000 of RAM just a few months later,” he posted on Facebook on Monday.
