Micron expects memory and storage supply-demand conditions to be tighter in 2027 and 2028 than in 2026, even as industry output grows. CEO Sanjay Mehrotra says the company cannot yet see when supply will catch up with demand. That is a forecast about industry conditions—not a specific prediction for retail RAM or SSD prices.
What Micron is forecasting
On Micron’s fiscal Q4 2026 earnings call, CEO Sanjay Mehrotra said, “We expect memory and storage supply demand conditions to be much tighter in calendar 2027 and 2028 than they were in 2026.” The company’s outlook distinguishes its fiscal-year reporting from the calendar-year market forecast: the tighter conditions he described are for calendar 2027 and 2028. Micron’s earnings-call transcript is the source for the forecast and the company’s estimates below.
Micron expects industry NAND bit shipments to grow by approximately the mid-20s percentage range in each of calendar 2027 and 2028, and industry DRAM bit shipments to grow by approximately the low-20s percentage range. These are management forecasts, not final shipment results or independently measured market statistics. Despite that expected growth, Micron says both markets will remain supply-constrained in those years.
Why supply may not keep pace with demand
AI is accelerating demand
Micron’s SEC filing says demand for memory and storage has grown faster than Micron and the wider industry could increase supply, driven in part by AI-related expansion in data centers. The filing also describes customers seeking long-term committed access to memory and the company making supply-allocation decisions. Micron’s Form 10-Q for the quarter ended May 28, 2026 sets out those demand and allocation pressures.

HBM uses more production space
High-bandwidth memory (HBM), used in AI systems, takes more wafers and cleanroom space to produce the same number of bits as conventional DRAM at the same technology node, according to Micron’s filing. Micron also expects HBM bit shipments to grow faster than conventional DRAM through calendar 2028. That growth can absorb manufacturing capacity even while conventional DRAM output rises.
Factories and production capacity take time
Micron cites structural limits on DRAM supply growth, the need for additional cleanroom space, and capacity demands associated with transitioning to newer manufacturing nodes. New facilities do not deliver large volumes of memory as soon as they begin output: Micron says production ramps gradually, with output becoming more meaningful a few quarters after initial production.

When Micron’s new facilities are expected to contribute
These are Micron’s projected initial-output milestones, as described on its fiscal Q4 2026 call. Initial wafer or facility output is not the same as full production or immediate relief across the market.
| Facility or project | Expected initial output | What that timing means |
|---|---|---|
| First Idaho fab | Mid-calendar 2027 | Micron expects wafer output to begin; volumes are expected to ramp gradually. |
| Singapore HBM advanced packaging | Early calendar 2027 | Expected packaging output, not a claim that all HBM demand will be met. |
| Second Idaho fab | Late calendar 2028 | Micron’s scheduled initial wafer output. |
| DRAM fab expansion in Japan | Late calendar 2028 | Micron’s scheduled initial output. |
| New Singapore NAND facility | Second half of calendar 2028 | Micron’s scheduled initial output. |
| First New York fab | Calendar 2030 | Not a near-term source of additional output; the date is Micron’s forecast. |
Micron’s July 9, 2026 U.S. investment announcement said the New York site had reached its first-concrete milestone and reiterated the Idaho timing. Those construction and output schedules are company expectations, not guarantees.

Mehrotra’s comments concern Micron’s business-to-business memory business, including HBM for AI systems and DRAM for servers. Ars Technica’s October 1, 2026 account of the warning notes that demand and supply allocation in those markets may have downstream implications for consumer devices. Ars Technica’s coverage provides that consumer-market context.
Micron’s outlook does not give a retail RAM or SSD price forecast, identify a consumer product that will be unavailable, or predict when consumer prices will fall. The company sells multiple forms of memory and storage—including components, modules, SSDs, managed NAND, multi-chip packages, and wafers—and those products do not necessarily share the same supply conditions. So “memory shortage” should not be read as a promise that every product will be equally scarce or more expensive.
Rank #4
How long could the shortage last?
Micron says it does not have line of sight to when supply and demand will return to balance. Its forecast points to tight industry conditions through calendar 2028, but it does not establish a precise date when the shortage ends. Output is expected to increase; the company’s point is that projected growth may still fall short of demand during that period.
