1Clear out junk files and repair common Windows errors2Scan for outdated or missing drivers - takes under a minute3Repair Windows errors before they cause bigger problemsAI data centers are adding demand for high-bandwidth memory (HBM), conventional DRAM and NAND storage faster than suppliers can expand and redirect production. The effects are not uniform: server-focused demand and capacity allocation are tightening DRAM availability, including PC memory, while NAND storage has a different forecast and may see supply ease later. HBM, DRAM and NAND perform different jobs, so there is no single shortage timeline for all three.
What “memory” and “storage” mean in an AI data center
The terms are often used loosely, but the parts are distinct. DRAM is volatile working memory: it holds information for quick access while a system is running. HBM is a form of DRAM built from stacked memory dies to provide very high bandwidth close to an AI accelerator. Conventional server DRAM supports CPUs and other system work. NAND flash is non-volatile storage, commonly used in SSDs, that retains data when power is off.

| Component | Typical role in AI infrastructure | What it is not |
|---|---|---|
| HBM | High-bandwidth access to data used by an accelerator, including model weights and active computations. | It is not a substitute for all server RAM or persistent storage. |
| Conventional DRAM | Working memory for server CPUs and system tasks. | It does not retain data when power is removed. |
| NAND flash | Persistent storage in SSDs, including enterprise workloads and data lakes. | It is not the same product market as DRAM. |
Micron describes data-center SSDs as serving persistent key-value (KV) cache and high-capacity data-lake roles. That does not mean all AI data is stored on NAND or that other storage, such as hard drives, has disappeared. The memory layers work together, but they are not interchangeable. Micron’s memory overview and its data-center storage material explain these product roles.

Accelerators need high-bandwidth memory
Training and inference involve repeatedly accessing model weights and intermediate data. HBM’s stacked design puts substantial memory bandwidth close to an accelerator, which is why demand for it is growing with AI deployments. Those systems also require conventional DRAM for CPU-side work and broader server operation; adding HBM does not eliminate the need for ordinary server memory.

Inference can expand memory needs
TrendForce identifies longer context windows and iterative, agent-style inference as factors that can raise demand. A model’s KV cache, which stores information used during generation, can grow with the amount of context and work being handled. TrendForce says this contributes to demand for both HBM and conventional DRAM. This is an industry analyst’s account of a demand driver, not a guarantee that every AI workload uses memory in the same way. TrendForce’s analysis discusses these workloads.
AI systems also need persistent storage
Data centers use SSDs for persistent information, and TrendForce reports rising enterprise SSD demand alongside AI and server deployments. That adds pressure to NAND supply, but NAND’s production outlook differs from DRAM’s. AI demand therefore affects multiple markets through separate products and supply chains, rather than through one generic “memory” component.

Why suppliers cannot quickly match demand
Micron’s Form 10-Q for the quarter ended May 28, 2026, states: “The AI-driven growth in the data center has accelerated demand for memory and storage at a rate greater than our ability and the industry’s ability to increase supply.” That is Micron’s own assessment in an SEC filing; the company is a primary source on its operations but also has a commercial interest in memory-market conditions. Micron’s filing contains the statement.

Capacity is being allocated toward AI products
Suppliers make choices about which products receive manufacturing capacity. TrendForce says manufacturers are directing capacity toward HBM and server products as AI server demand remains strong. HBM also takes more wafer input than conventional DRAM, so shifting production toward HBM can limit the amount of wafer capacity available for ordinary DRAM even while total output rises. This helps explain why PC DRAM can tighten without every memory product facing the same conditions. TrendForce’s July 2026 outlook details these supply constraints.

New fabs take years to contribute meaningfully
Micron’s February 2026 SEC filing sets out planned supply timelines at several sites. These are projected milestones, not evidence that the capacity is already producing memory at scale.
| Site | Micron’s stated timeline | How to interpret it |
|---|---|---|
| Boise, Idaho fab | Projected first DRAM wafer output in mid-2027. | First wafer output is a milestone; it does not mean full production capacity is immediately available. |
| Second Idaho fab | Expected to be operational by the end of 2028. | A company projection, not completed capacity. |
| New York DRAM site | Anticipated supply window in 2030 and beyond. | A longer-term planned supply source. |
TrendForce likewise says DRAM capacity planned for 2027 is not expected to contribute substantial output until 2028, reflecting construction, equipment installation and manufacturing ramp-up. Micron’s filing describes its site plans.

Why PC RAM can be affected even though the demand is in data centers
PCs and servers both use DRAM, so they draw on related production capacity. TrendForce says reallocating capacity toward HBM and server products is reducing PC DRAM availability. The result can be tighter supply and upward price pressure for consumer RAM, but it does not mean every PC memory product or market has the same price or availability.
Price movements also reflect demand, not just supply. In its 3Q26 survey, TrendForce said weakening consumer demand was moderating the pace of price increases. That is a qualification to the shortage story: reduced PC DRAM supply can coexist with softer consumer demand, and the balance can change by quarter and product. The survey describes a market trend, not a live retail price list. TrendForce’s 3Q26 survey provides that consumer-demand context.

Why DRAM and NAND have different shortage outlooks
TrendForce’s July 2026 outlook expects DRAM to remain constrained, while NAND supply may ease in the second half of 2027 if planned new capacity ramps as expected. The NAND view is conditional: a planned ramp is not guaranteed output. Do not apply the DRAM outlook or timeline automatically to SSDs, or assume NAND will ease on that date regardless of execution and demand. TrendForce’s outlook is the more recent product-level forecast in this comparison.
TrendForce estimated the 2026 DRAM sufficiency ratio at approximately -1% to -2% in its July 2026 forecast. This is a forecast metric for estimated supply relative to demand, not a direct count of global inventory. It signals a tight balance, but it should not be read as a precise measure of how many memory chips are available to a particular buyer.
What market-size forecasts do—and do not—tell you
TrendForce raised its 2026 global memory-market revenue forecast to US$889.3 billion. In a May 2026 forecast, it projected more than US$1.28 trillion for 2027, about 44% annual growth in that forecast. These are revenue forecasts, not measurements of physical chip output or an assurance that every category will be short. Forecasts can change; TrendForce’s later July product-level outlook is more useful for comparing the expected DRAM and NAND balance. TrendForce’s market forecast gives the revenue estimates.

When will the shortage end?
There is no single end date because “memory and storage” covers markets with different products, capacity plans and demand. The available outlook points to continuing DRAM constraints and a possible NAND supply easing in the second half of 2027 if new capacity ramps as planned. Micron’s disclosed projects add supply milestones from mid-2027 through 2030 and beyond, but those are staged plans rather than an immediate industry-wide fix.
For buyers, the practical implication is to judge the component they need, not a general shortage headline. A PC owner considering a RAM upgrade should check the computer’s supported memory generation, capacity and form factor, then compare current listings for a compatible kit. Buying RAM may meet that owner’s need, but it does not resolve the wider supply balance.
