RAM is a critical component of any computer system – including industrial platforms. It enables fast data processing and ensures stable system performance. Since mid-2025, however, growing supply constraints have begun to affect the global RAM market. Module availability is declining, prices are rising sharply, and lead times are becoming increasingly extended. As a result, device manufacturers are being forced to factor higher component costs into their pricing and project calculations.
The primary driver behind this situation is the rapid expansion of artificial intelligence. Large-scale data centers now consume a significant share of global memory production, prompting manufacturers to prioritize high-capacity solutions for AI infrastructure over standard modules commonly used in industrial computers. Consequently, companies must prepare for higher procurement costs, longer delivery times, and increased uncertainty in project planning.
In this article, we examine the root causes of the current RAM shortage, its impact on the market, and the outlook for the coming years. We also outline practical strategies to help mitigate the risk of production delays and rising costs.
What Is RAM and Why Is It Critical in Industrial Computers
Random Access Memory (RAM) is the system’s working memory, where data is temporarily stored for immediate processing. Its contents are cleared once the power is turned off, but while the system is running, RAM plays a central role in ensuring speed, responsiveness and overall performance.
In industrial computers, RAM is particularly important. It enables efficient multitasking, supports HMI systems, PLC controllers and SCADA applications, and allows real-time buffering of data from sensors, cameras and communication interfaces. When available memory is insufficient, the system may experience latency, reduced performance or even stability issues – all of which can disrupt industrial operations.
In this context, RAM is not just a technical specification. In industrial hardware, it is also a significant cost component. Any increase in RAM prices directly affects the overall price of the device.
Under current market conditions, this has become especially relevant for companies planning long-term projects or large-scale deployments, where component price fluctuations can substantially impact total investment costs.
Why Is There a RAM Shortage – Key Drivers
Surge in AI-Driven Memory Demand
The primary cause of the current shortage is the rapid expansion of artificial intelligence. Modern data centers running advanced AI models require vast amounts of memory – significantly more than traditional server environments. Global technology companies are investing billions in expanding their infrastructure, and memory manufacturers are securing long-term supply agreements to meet this demand.
In practice, this means that a substantial share of global memory production is now allocated to the AI sector rather than to consumer electronics or industrial applications.
Estimates suggest that by 2026, data centers could account for as much as 70% of total memory consumption worldwide. As a result, standard DDR4 and DDR5 modules – commonly used in industrial computers – are becoming increasingly difficult to source.
Phase-Out of DDR4 and Reduced Supply
The situation is further complicated by an ongoing technology transition. Memory manufacturers are gradually phasing out DDR4 production, shifting capacity toward newer and more profitable solutions such as DDR5 and high-performance memory designed specifically for AI systems.
For many industrial companies, this creates a significant challenge. Industrial projects are often planned with a multi-year lifecycle in mind, and many existing platforms still rely on DDR4. As production volumes decline, certain DDR4 modules are now available only in limited quantities, with lead times stretching to several dozen weeks in some cases.
As a result, companies must either secure supply well in advance or consider redesigning their hardware platforms to accommodate newer memory standards.
Market Consolidation and Geopolitical Factors
The global memory market is dominated by a small number of major manufacturers. When these players simultaneously prioritize AI-driven demand, the availability of conventional memory modules is directly affected.
In addition, a significant share of memory production is concentrated in East Asia, which increases exposure to geopolitical risks and potential logistical disruptions. Even temporary issues in one region can quickly translate into global supply constraints.
A Structural Shift in Demand
Unlike previous shortages driven by short-term market cycles, the current situation appears to be more structural in nature. The rise of AI is not a temporary trend but a long-term transformation of the technology landscape.
Industry analysts expect demand for advanced memory solutions to remain high for the next several years. This suggests that tight supply of standard RAM modules may persist beyond 2027, and companies should factor this reality into their long-term strategic planning.
Impact of the Shortage on the Market
Rising RAM Prices and More Expensive Industrial Computers
The most immediate and visible consequence of the RAM shortage is rising prices. In recent months, DRAM module prices have increased significantly, directly affecting the production costs of electronic devices.
In industrial computers, memory can account for as much as 15–25% of total component value. As a result, even moderate price fluctuations in RAM modules can noticeably impact the final system price.
The sharpest increases are typically seen in higher-capacity configurations, such as 32 GB and 64 GB. A good example is the industrial Box PC SF101-ADS (DFI), which supports up to 64 GB of DDR4 memory across two SO-DIMM slots. Platforms of this type offer substantial flexibility in terms of memory configuration and scalability.
However, in a volatile RAM market, careful forward planning becomes essential. Defining the target memory capacity early in the project and securing supply in advance can help reduce the risk of cost escalation and project delays.
Longer Lead Times for RAM Modules
The RAM shortage is not only driving prices upward – it is also significantly extending delivery times. In many cases, lead times for DDR4 and DDR5 modules now exceed 20–30 weeks, and some orders are fulfilled under allocation policies, meaning that available volumes are strictly limited.
In practical terms, this directly affects the production schedules of industrial computers, particularly those configured to meet specific customer requirements. For operator panels using DDR5 memory – for example, configurations supporting up to 16 GB in SO-DIMM format – the final memory capacity often needs to be defined at the time of order placement.
In embedded projects, an alternative approach involves platforms with onboard (soldered) memory. In this model, RAM capacity is determined during module manufacturing, which simplifies long-term planning. However, it also limits the possibility of future upgrades once the system is deployed in the field.
Specification Changes and the Phase-Out of DDR4
Fluctuating RAM availability can significantly impact industrial project planning, particularly for platforms based on DDR4 SO-DIMM modules. These solutions are valued for their flexibility and serviceability, allowing memory configurations to be adjusted in response to market conditions.
However, in long-lifecycle industrial projects, effective component lifecycle management becomes critical. In the industrial sector, Product Change Notifications (PCN), Engineering Change Notices (ECN) and End-of-Life (EOL) announcements are standard mechanisms used to communicate specification updates or planned product discontinuations.
In the case of DDR4, this may include a Last Time Buy (LTB) notice – the final opportunity to purchase a specific module before production is discontinued.
For this reason, selecting an industrial computer should involve not only evaluating current performance parameters but also assessing the long-term availability strategy for key components. Proactive measures – such as securing buffer stock, qualifying alternative suppliers or preparing a migration path to DDR5-based platforms – can significantly reduce the risk of costly redesigns during the lifecycle of a project.
Outlook and Conditions for Market Stabilization
Forecast for 2026–2028
Current indicators suggest that the RAM shortage is not a short-term disruption. Market analysts expect constrained availability to persist at least through 2027, with meaningful stabilization of supply and pricing unlikely before 2028.
In practical terms, companies should assume that elevated prices and extended lead times will remain the norm throughout 2026–2027. Strategic planning during this period must take into account continued volatility in both availability and procurement costs.
Industry reports also indicate that supply constraints may impact sales of finished devices. Global shipments of smartphones and PCs are forecast to decline in 2026, highlighting that the issue extends beyond component manufacturers and affects the broader IT ecosystem – including the industrial computing sector.
Although leading memory manufacturers are investing heavily in new fabrication facilities, most of these plants are scheduled to become fully operational only in 2027–2028. Until then, the market is expected to operate under conditions of limited supply and intense competition for available production capacity.
What Needs to Happen for the RAM Market to Stabilize?
Ending the current RAM crisis will require tangible changes across manufacturing and the broader supply chain.
- Increased DRAM production capacity – The most critical factor is bringing new fabrication plants online and expanding overall production capacity. Without a meaningful increase in supply, RAM prices are likely to remain elevated.
- Technological improvements in manufacturing – Memory producers are working to enhance production efficiency and increase memory density. Advances in process technology could improve availability without relying solely on the construction of multiple new facilities.
- Supply chain diversification – Reducing dependence on a single geographic region – particularly East Asia – would strengthen supply resilience in Europe and North America. A more geographically balanced production footprint would help mitigate regional disruptions and geopolitical risks.
- Stabilization of AI-driven demand – Artificial intelligence is currently the primary engine of memory demand. If the pace of AI infrastructure investment levels off, or if alternative technologies reduce memory intensity, pressure on standard RAM modules could ease.
At present, however, all signs indicate that companies relying on RAM – including industrial computer manufacturers – must adopt a multi-year planning horizon rather than expecting short-term normalization.
Long-Term Projects
In long-lifecycle projects, the declared availability of the hardware platform becomes a decisive factor. A relevant example is the COMe 10M-EHL module (Engicam), equipped with LPDDR4 memory (2–16 GB), for which the manufacturer guarantees availability until 2032.
Such long-term availability commitments significantly simplify investment planning in industrial environments, where product lifecycles often exceed 5–7 years and require a predictable, stable supply chain.
