What does the future hold for the market?

The "super cycle" of memory driven by artificial intelligence is accelerating comprehensively, compelling major global suppliers to significantly raise prices while pushing customers to secure long-term supply arrangements to mitigate escalating risks of shortages.

Nomura predicts that the memory supercycle starting in 2023 will extend through 2027, creating unprecedented revenue levels.

The primary drivers of this cycle are robust demand from AI servers and traditional servers (used for conventional cloud and AI inference). Meanwhile, due to long equipment lead times (6-9 months), even if the industry accelerates capacity ramp-ups in existing cleanrooms, the impact on supply growth in 2026 will remain limited.

Nomura expects meaningful acceleration in industry-wide capacity and production growth to emerge only in the mid-to-late 2027 period, leading to a multi-year period of sustained undersupply.

According to media reports on the 23rd, Samsung Electronics and SK Hynix have raised prices of their DRAM and NAND flash memory by up to 30% in the fourth quarter, passing on the new pricing framework to customers. This move directly responds to the current imbalance in market supply and demand, officially initiating an upward price cycle.

The market broadly anticipates,This AI-driven supply shortage is expected to last longer and be more intense than any previous boom cycle. Analysts cited in the report suggest that the shortage could persist for three to four years.Behind this forecast lies a confluence of factors, including millions of trillions of Korean won in new investments for AI servers, ongoing memory upgrades for general-purpose servers, and rising demand for AI-enabled devices on the edge.
