Nvidia Supplier SK Hynix Says HBM Chips Almost Sold Out for 2025

South Korea's SK Hynix said on Thursday that its high-bandwidth memory (HBM) chips used in AI chipsets were sold out for this year and almost sold out for 2025 as businesses aggressively expand artificial intelligence services.

The Nvidia supplier and the world's second-largest memory chipmaker will begin sending samples of its latest HBM chip, called the 12-layer HBM3E, in May and begin mass producing them in the third quarter.

"The HBM market is expected to continue to grow as data and (AI) model sizes increase," Chief Executive Officer Kwak Noh-Jung told a news conference. "Annual demand growth is expected to be about 60% in the mid-to long-term."

SK Hynix which competes with US rival Micron and domestic behemoth Samsung Electronics in HBM was until March the sole supplier of HBM chips to Nvidia, according to analysts who add that major AI chip purchasers are keen to diversify their suppliers to better maintain operating margins. Nvidia commands some 80% of the AI chip market.

Micron has also said its HBM chips were sold out for 2024 and that the majority of its 2025 supply was already allocated. It plans to provide samples for its 12-layer HBM3E chips to customers in March.

"As AI functions and performance are being upgraded faster than expected, customer demand for ultra-high-performance chips such as the 12-layer chips appear to be increasing faster than for 8-layer HBM3Es," said Jeff Kim, head of research at KB Securities.

Samsung Electronics, which plans to produce its HBM3E 12-layer chips in the second quarter, said this week that this year's shipments of HBM chips are expected to increase more than three-fold and it has completed supply discussions with customers. It did not elaborate further.

Last month, SK Hynix announced a $3.87 billion plan to build an advanced chip packaging plant in the US state of Indiana with an HBM chip line and a 5.3 trillion won ($3.9 billion) investment in a new DRAM chip factory at home with a focus on HBMs.

Kwak said investment in HBM differed from past patterns in the memory chip industry in that capacity is being increased after making certain of demand first.

By 2028, the portion of chips made for AI, such as HBM and high-capacity DRAM modules, is expected to account for 61% of all memory volume in terms of value from about 5% in 2023, SK Hynix's head of AI infrastructure Justin Kim said.

Last week, SK Hynix said in a post-earnings conference call that there may be a shortage of regular memory chips for smartphones, personal computers and network servers by the year's end if demand for tech devices exceeds expectations.

The world's deadliest tsunami hit nations around the Indian Ocean two decades ago before social media platforms flourished, but they have since transformed how we understand and respond to disasters -- from finding the missing to swift crowdfunding.

When a 9.1-magnitude quake caused a tsunami that smashed into coastal areas on December 26, 2004, killing more than 220,000 people, broadcasters, newspapers and wire agencies were the main media bringing news of the calamity to the world.

Yet in some places, the sheer scale took days to emerge.

Survivor Mark Oberle was holidaying in Thailand's Phuket when the giant waves hit Patong beach, and penned a blog post to fend off questions from family, friends and strangers in the days after the disaster.

"The first hints of the extent were from European visitors who got text messages from friends back home," said Oberle, adding people initially thought the quake was local and small, when its epicenter was actually near western Indonesia, hundreds of miles away.

"I wrote the blog because there were so many friends and family who wanted to know more. Plus, I was getting many queries from strangers. People were desperate for good news tales," said the US-based physician, who helped the injured.

The blog included images of cars ploughed into hotels, water-filled roads and locals fleeing on scooters because rumors produced "a stampede from the beach to higher ground".

Bloggers were named "People of the Year" by ABC News in 2004 because of the intimacy of first-hand accounts like those published in the days following the tsunami.

But today billions can follow major events in real-time on social media, enabling citizen journalism and assistance from afar, despite the real risk of rumor and misinformation.

During Spain's worst floods for decades in October, people voluntarily managed social media accounts to assist relatives trying to locate their missing loved ones.

After Türkiye's devastating earthquake last year, a 20-year-old student was rescued thanks to a post of his location while buried under the rubble.

- 'Fast picture' -

Two decades ago, the online social media landscape was vastly different.

Facebook was launched early in 2004 but was not yet widely used when the tsunami hit.

One of YouTube's founders reportedly said an inspiration for the platform's founding in early 2005 was an inability to find footage of the tsunami in its aftermath.

Some tsunami images were posted on photo site Flickr. But X, Instagram and Bluesky now allow for instant sharing.

Experts are clear that more information saves lives -- hours lapsed between the tremor's epicenter near Indonesia and the giant waves that crashed into Sri Lanka, India and Thailand's coastal areas.

Daniel Aldrich, a professor at Northeastern University, conducted interviews in India's Tamil Nadu where many said they had no idea what a tsunami was and had no warnings in 2004.

"In India alone nearly 6,000 people were taken by surprise and drowned in that event," he said.

Mobile apps and online accounts now quickly publicize information about hospitals, evacuation routes or shelters.

"Social media would have provided an immediate way to help locate other survivors and get information," said Jeffrey Blevins, head of journalism at the University of Cincinnati.

Oberle also noted that "knowing what help was locally available... would have provided a clearer perspective of what to expect in the days to come".

- Citizen science -

Beyond emergency rescue, social media clips can also be a boon to understanding a disaster's cause.

When giant waves crashed into Indonesia's Aceh province, footage remained largely confined to handheld camcorders capturing the carnage.

Fast forward to 2018, when a quake-tsunami hit Indonesia's Palu city, killing more than 4,000 people, enough videos were taken on smartphones that scientists researching seismic activity were later able to use the clips to reconstruct its path and time between waves.

The piece of citizen science in 2020 used amateur videos to conclude it happened so fast because of underwater landslides close to shore.

But it's not all good news.

Scholars warn that disinformation and rumors have also hindered disaster responses.

When Hurricane Helene struck North Carolina in September, relief efforts were disrupted as tensions between locals and emergency workers rose over unfounded rumors including a higher hidden death toll and diverted aid.

Workers faced reported threats from local armed militias.

"This information was so malicious that FEMA (Federal Emergency Management Agency) had to withdraw its teams from the area," said Aldrich.

"Social media has absolutely altered the field of disaster response for the good and the bad."

Yet perhaps the biggest change -- the free flow of information to the vulnerable -- has been beneficial.

Laura Kong of the Honolulu-based International Tsunami Information Center recently recalls how "2004 was such a tragedy".

"Because... we might have known there was an event, but we didn't have a way to tell anyone."
