The global semiconductor memory industry is currently going through a historic “super cycle” driven by AI. Unlike past cycles led by PCs and smartphones, this one is powered by AI—reshaping the market, technology, and competitive landscape.

1. Market Status: A “Super Cycle” of Rising Prices and Demand
The memory market is experiencing a rare supply shortage, driving up both prices and profits.
Record market size: The global semiconductor memory market is expected to exceed $600 billion in 2026.
Rising prices: Supply-demand imbalance is pushing prices higher.
In Q1 2026, contract prices for conventional DRAM are expected to rise 90–95%, while NAND flash prices are projected to increase 55–60%. Goldman Sachs predicts DRAM supply will see its largest shortfall in 15 years.

2. Key Driver: AI Is Reshaping Memory Demand
AI is shifting from a compute-centric model to one where memory plays a central role. High-performance memory has become a bottleneck for AI system efficiency and a core strategic resource.
HBM becomes the “golden track”: High-bandwidth memory (HBM), integrated closely with processors, solves the “memory wall” issue in large AI models and has become standard in AI accelerators. The global HBM market is expected to reach $54.6 billion in 2026, accounting for nearly 40% of the DRAM market.
Structural shortages are the new normal: Building new fabs takes 2–3 years, and manufacturers are directing over 70% of new capacity toward high-end products like HBM. This reduces supply for consumer-grade memory chips (such as DDR4 and low-end NAND), tightening availability across all segments.

3. Competitive Landscape and Industry Restructuring
Competition has shifted from capacity expansion to technological value, and the market is moving from pure oligopoly toward a more diverse landscape.
The big three: Samsung, SK Hynix, and Micron are focusing on high-margin segments like HBM and DDR5, securing key technological positions.
Chinese players gaining ground: Manufacturers like YMTC and CXMT have made breakthroughs in technology and market share, gradually entering mainstream global supply chains.

4. Impact and Risks for Downstream Industries

Higher end-product prices: Memory now accounts for over 30% of total BOM costs in many devices—up from around 20% in the past, with some high-end models exceeding 35%. This is pushing up prices for smartphones, computers, and other electronics.

In 2026, the semiconductor memory industry is undergoing a structural shift driven by AI. High-end products like HBM are becoming the main growth drivers, and supply shortages across all segments are expected to continue through 2027 or longer. For industry players, this is a critical test of technical capability and supply chain resilience. For consumers, higher memory costs in electronics are becoming an unavoidable reality.
