Memory Makers Warn AI-Driven RAM Shortages Will Persist Through 2028
Executives at Micron and Samsung report that the global memory crunch will continue through at least 2028 as explosive AI demand absorbs wafer capacity and drives up hardware costs.
AI Hardware Demand Locks Up Memory Supply Through 2028
Global memory supplies will remain severely constrained through at least 2028 as artificial intelligence infrastructure consumes manufacturing output, according to top semiconductor executives. Speaking to investors, Micron CEO Sanjay Mehrotra stated that demand across the company's business-to-business memory portfolio—primarily high-bandwidth memory (HBM) and server DRAM—will consistently exceed production capacity over the coming years. Mehrotra warned that the overall balance between supply and demand is only growing tighter.
Capacity Bookings and Architectural Transitions Constrain Output
Micron has already committed 75 percent of its planned memory capacity for 2027, with the company's contract discussions now centering primarily on 2028 shipments. Mehrotra revealed that a substantial volume of 2027 HBM output is sold out at pricing substantially higher than 2026 levels. Driving this run on capacity is the rapid scaling of artificial intelligence: Mehrotra cited larger model architectures, expanding context windows, heightened concurrency, and the deployment of autonomous enterprise and consumer agents as persistent drivers of higher memory content and performance requirements.
Relief from new manufacturing facilities remains years away. While Micron plans to bring new clean rooms online in 2028, Mehrotra cautioned that production ramps slowly even after initial wafer output begins. Compounding the supply squeeze are fabrication challenges tied to architectural generational leaps. As manufacturing migrates from HBM3E to denser HBM4 and HBM4E configurations, trade ratios require more wafer area per package, while advanced node transitions deliver diminishing productivity gains per wafer.
Industry Shift Squeezes Consumer Hardware
The enterprise AI boom is actively starving the consumer hardware supply chain. Kim Taewoo, executive vice president at rival memory maker Samsung, noted that HBM is projected to consume nearly 30 percent of the DRAM industry's total wafer capacity by 2027, up from roughly 20 percent in 2026.
This production tilt toward high-margin data center infrastructure prompted Micron to exit the consumer RAM market entirely under its Crucial brand following a December 2025 announcement. At the time, Micron EVP and Chief Business Officer Sumit Sadana pointed to overwhelming data center demand and the need to back strategic customers in fast-growing sectors. Consequently, consumer tech faces significant downstream pressure: PC manufacturers have begun reducing baseline RAM capacities while raising prices, while retail costs for smartphones, streaming hardware, and gaming consoles continue to climb.
