Sam Altman wants the memory in your laptop.
He told a podcast it is “quite terrible” that the world's limited supply of DRAM sits in personal computers. Two days later he was in Yongin, in front of fifty Samsung executives.
On Saturday, Sam Altman stood in a training centre in Yongin, south of Seoul, in front of about fifty Samsung executives. Not only chip people — Samsung brought in its finance and biotech arms too. The stated subject was what AI does to industries over the next decade.
Two days earlier he had said something on a podcast that makes the trip easier to read. He said it was “quite terrible” that the world's limited supply of DRAM sits in people's own computers.
What DRAM is
It is the fast, forgetful memory. Think of a desk and a filing cabinet. The hard drive is the cabinet: slow, large, and it keeps things when you go home. DRAM is the desk: whatever you are working on right now is spread across it, and it is wiped clean every time the power goes off.
Your laptop has some. A phone has less. A machine training a large model wants an amount that would not fit on any desk you have ever owned.
Why AI is so hungry for it
A model has to have its numbers somewhere the processor can reach quickly, and a processor that waits for memory is a processor you are paying for and not using.
So the industry stacks the memory in layers and puts it right beside the chip. That is high-bandwidth memory, and it is made on the same lines, from the same wafers, as the memory in a laptop.
That last point is the whole story. It is one pool. A chip sold into a data centre is a chip not sold into a consumer machine.
What was actually agreed in Yongin
Nothing new, as far as anyone has said.
The arrangement already existed: Samsung and SK Hynix signed letters of intent in October 2025 to supply high-bandwidth memory for Stargate, with plans to scale up to around 900,000 such chips a month. Reports of the Yongin meeting describe it as reaffirming that, and several note explicitly that no fresh supply deal was announced.
Treat the coverage with some care. Some outlets framed the visit as deepening cooperation, others as a response to a memory shortage, and those are not the same claim.
The idea to take away
When the chief executive of the largest buyer of memory in the world says publicly that it is a shame so much memory is sitting in ordinary computers, he is not making an observation. He is describing where he would like the supply to go.
You will not see this as a headline. You will see it as the price of a memory upgrade, quietly not falling the way it used to.
