Has AI Ended the Memory Chip Boom and Bust Cycle for Good?

Micron crossed $1 trillion in market worth this week, a milestone that might have sounded absurd to most buyers even just a few years in the past. The memory-chip enterprise has lengthy been one of many cruelest corners of tech: brutal booms adopted by catastrophic busts.

I’ve coated this story earlier than. Again in 2017, I wrote about Solar Microsystems co-founder Invoice Pleasure arguing that the DRAM market had lastly modified for good. His thesis was that fewer suppliers and rising demand from cloud computing and AI would scale back the business’s historic tendency to destroy itself by means of overproduction.

That argument turned out to be early, not mistaken.

Micron shares have soared roughly twentyfold since then. Samsung crossed the $1 trillion market-cap threshold earlier this month, and SK Hynix joined the social gathering on Tuesday. There are fundamentals behind these strikes: Samsung made greater than $30 billion in revenue throughout the first quarter alone.

Now buyers are asking essentially the most harmful query in finance: Is that this time completely different?

Possibly.

The primary huge change is consolidation.

Within the early Nineteen Nineties, there have been greater than 20 significant DRAM makers globally. Right now, the business is successfully managed by three corporations: Samsung, SK Hynix, and Micron.

For many years, reminiscence makers responded to rising demand by flooding the market with new provide. Costs finally collapsed and income evaporated. Fewer rivals might imply fewer incentives to repeat that cycle.

The second change is AI demand itself.

Fashionable AI methods are ravenous consumers of memory as a result of they always transfer and course of big quantities of knowledge inside large information facilities. Even superior methods designed to scale back computing bottlenecks nonetheless run into reminiscence constraints. Startup Lightmatter is utilizing photonics — primarily mild as a substitute of copper — to hurry up AI information facilities, however CEO Nick Harris advised me not too long ago that this does nothing to get rid of the memory bottleneck.

So, rampant AI demand is colliding with constrained provide. UBS analysts noted this week that reminiscence makers are signing multi-year agreements with cloud giants that lock in each quantity commitments and partially fastened pricing. That ought to add one other layer of stability. UBS estimates these offers may hold the DRAM market undersupplied into 2028.

After all, this might nonetheless show to be an unusually giant up-cycle that finally ends. The remaining gamers may flood the market once more. New entrants may emerge. AI demand may cool, or a brand new know-how would possibly scale back the necessity for reminiscence.

However buyers clearly consider the outdated reminiscence enterprise might lastly be changing into one thing new.
