Dwindling supplies and soaring costs of Dynamic Random Access Memory (DRAM) that provides space for computers, smartphones, and game consoles to run applications or multitask was a hot topic behind the scenes at the annual gadget extravaganza in Las Vegas.

Once cheap and plentiful, DRAM -- along with memory chips to simply store data -- are in short supply because demand spiked by AI in everything from data centers to wearable devices.

"Everybody is screaming for more supply...they just can't find enough," Sangyeun Cho, who is responsible for Samsung Electronics' semiconductor business in the US, told AFP.

"And AI demand is still mounting."

DRAM and memory chip makers have shifted manufacturing capacity to cater to AI data centers.

Meanwhile, AI features being added to all kinds of products have increased the need for DRAM and memory in devices from laptops to smart rings.

The global semiconductor ecosystem is facing an unprecedented memory chip shortage that could persist well into next year, according to market tracker IDC.

"What began as an AI infrastructure boom has now rippled outward, with tightening memory supply, inflating prices, and reshaping product and pricing strategies across both consumer and enterprise devices," IDC analysts said in a blog post.

"For consumers and enterprises alike, this signals the end of an era of cheap, abundant memory and storage."

Costs of computers, drives and memory cards have already risen for consumers, according to Other World Computing founder and chief Larry O'Connor.

- Sniff not bark -

Gadget makers are adapting to the shortage by either paying premiums for DRAM and memory, redesigning their products, or foregoing some features, according to Michal Siwinski of Arteris, which specializes in providing connectivity inside chips.

"Maybe the (robotic) dog you'll get will sniff around and roll over, but it's not going to bark a serenade because it doesn't have enough memory," Siwinski said.

The shortage is already forcing efficiencies such as engineers writing tighter code to provide performance using less memory, according to O'Connor.

"These aren't bad things; they should have already happened," O'Connor said.

"The entire industry has been built around cheap software that has become very bloated over the last 20 years."

However, gadget makers must avoid their products underperforming due to memory compromises or pushing prices up too high by paying dearly for components, warned Techsponential analyst Avi Greengart.

"Here at CES we're still seeing the usual claims that our thing is the best and damn the RAM cost," Greengart said on the show floor.

"However, if you spend time in suites talking to (device makers), retailers and component manufacturers you get a very different story."

That story is that modifications will be made to keep prices in line with consumer expectations, according to Greengart.

The shortage vexing memory chips is being watched warily by other sectors, particularly companies that rely on semiconductors needed to power AI.

These powerful semiconductors and analog parts have "nothing to do" with DRAM, but companies are vigilant for any spillover effects, Infineon Technologies chief executive Jochen Hanebeck told AFP.

German semiconductor titan Infineon specializes in powering AI, a market where the amount of computing taking place is expected to continue rocketing.

"Customers are asking about capacities, and I think they have seen the lessons learned on DRAM, and that's why they are very mindful," said Hanebeck.

"There is a good chance for a shortage; it is a real challenge to manage that supply chain."
