Memory Chips: Why AI Demand Is Raising Prices

Text to type: Memory chips hold information inside electronic devices. Three important types are DRAM, NAND, and HBM. They do different jobs. DRAM is short-term working memory, often called RAM. It holds information that a device is using now. Think of it as a kitchen work surface, with everything ready for the current job. NAND is long-term storage. It keeps photos, apps, and files even when the power is off. Phones and solid-state drives, or SSDs, use NAND. HBM means high-bandwidth memory. It stacks DRAM chips on top of each other and moves information very quickly. AI systems use it to keep their powerful processing chips supplied with information.

Text to type: An AI data center is a building full of server computers that run AI services. These computers need memory for larger AI models, longer conversations, and many users at the same time. AI agents, which carry out tasks, add more demand. Fast processing chips also need information to arrive quickly. HBM helps meet that need. As AI server demand grows, factories put more effort into making HBM. A wafer is a thin, round piece of material on which chips are made. HBM needs more wafer space than ordinary DRAM. Samsung says HBM uses about 20% of global DRAM wafer capacity now. That share could reach close to 30% in 2027, leaving less capacity for other memory.

Text to type: The pressure was already clear in late 2025. PC and phone makers shipped devices early to avoid later memory price rises. In 2026, memory became more expensive. A contract price is a price agreed between a supplier and a buyer. The contract price of a 16-gigabit DDR5 DRAM chip reached $48 in September 2026, up from $45 in July. Further increases are forecasts, not completed changes. TrendForce expects ordinary DRAM contract prices to rise another 10–15% in late 2026, and NAND prices by 15–20%. For 2027, it forecasts a 121% rise in HBM’s average selling price. Separately, industry estimates suggest a 12-high, 36GB HBM4 stack could rise from about $600 in 2026 to about $1,300 in 2027.

Text to type: Three companies effectively share the HBM market: SK hynix, Samsung Electronics, and Micron Technology. SK hynix remains the leader. In the second quarter of 2026, it had about 50% of HBM revenue. Samsung is catching up fast. Its share rose from 21% to 33% in the comparison reported by Counterpoint Research. Both Samsung and SK hynix began mass-production shipments of HBM4 in 2026. Micron already has contracts for most of its 2027 HBM output. That means much of next year’s supply already has buyers. The shortage also reaches NAND. Japan’s Kioxia said in January that its whole 2026 NAND flash production was already sold out. AI demand affects storage as well as working memory.

Text to type: More factories sound like a simple answer, but building them takes years. Memory production needs special buildings, equipment, and carefully controlled conditions. Even after a factory is ready, production grows slowly. Micron CEO Sanjay Mehrotra says the balance between supply and demand is getting tighter. Micron and Samsung executives expect the shortage to continue into 2028. Micron plans new clean rooms in 2028, but those rooms will not immediately produce memory at full speed. Meanwhile, the business is growing sharply. South Korea’s memory chip exports rose 358.6% in September 2026 compared with a year earlier. Strong export growth can happen alongside a shortage. Suppliers can earn more while buyers struggle with higher prices and limited supply.

Text to type: The shortage reaches ordinary shops through higher prices and smaller memory amounts. PCs and phones may cost more, or offer less at the same price. IDC gives a clear example. A phone that previously offered 12GB of RAM and 256GB of storage may offer only 8GB and 128GB at the same price. PCs may also come with less RAM and smaller SSDs. Cheaper devices are especially affected. There are fewer consumer choices, too. Micron announced in December 2025 that its Crucial brand would stop selling RAM to consumers. These changes make replacement less attractive. Many people may keep old devices longer or buy used phones. The important comparison is now both price and what that price includes.
