How DRAM Will Change the World

DRAM, or Dynamic Random Access Memory, has long surpassed the narrow technical definition of “computer memory.” It is not only the central nervous system that powers the digital world, but also a strategic chip in national technology competition and the computing power foundation of the AI era.

In 1966, the renowned American electrical engineer Robert Dennard invented the single-transistor memory cell for DRAM, laying the foundation for modern electronic memory storage. DRAM not only replaced early magnetic memory technologies, but also became one of the fundamental technologies of the semiconductor industry. It has profoundly changed human society, from the way people work and entertain themselves to the way nations build digital infrastructure and even conduct modern warfare.

To understand how DRAM is changing the world from multiple dimensions, we can analyze it across five levels: technology, industry, economy, geopolitics, and society.

Global Procurement Insight:

For global electronics buyers, server manufacturers, AI hardware companies, and memory distributors, DRAM is no longer a simple commodity component. It has become a strategic sourcing category that directly affects product cost, delivery schedule, AI computing performance, and long-term supply chain resilience.

1. Technical Dimension: From Flat to Three-Dimensional, Breaking Through the Storage Wall

DRAM is an indispensable workbench in computing systems, responsible for high-speed data exchange with processors. Its technological evolution is redefining the boundaries of computing.

1.1 HBM: The Bandwidth Revolution in the AI Era

In the era of rapid development of artificial intelligence and high-performance computing, the memory bandwidth bottleneck has become a key factor limiting the performance improvement of computing systems. Due to physical limitations and energy consumption challenges, traditional memory architectures are no longer sufficient to meet the massive data throughput requirements of modern AI training and inference.

High Bandwidth Memory, or HBM, has emerged as a revolutionary 3D stacked memory technology. Through innovative technologies such as vertical stacking and through-silicon via, or TSV, HBM achieves a leap in memory bandwidth while significantly reducing power consumption and physical space occupation.

Core Innovations of HBM

3D stacked architecture: Multiple layers of DRAM chips are vertically stacked, currently up to 12 layers, significantly improving storage capacity per unit area.
Through-silicon via technology: Microscopic holes with a diameter of only 5 to 10 microns are etched inside stacked DRAM chips and filled with conductive materials to form vertical channels.
Silicon interposer: The silicon interposer acts as a precise bridge connecting the HBM stack and the processor. It achieves millimeter-level or even shorter interconnection distances, greatly reducing signal delay.

At present, the single-stack bandwidth of HBM3E has reached 1.2TB/s, and HBM4 is expected to further increase this figure to 2.0TB/s.

Samsung’s HBM4 adopts a 10-nanometer sixth-generation, or 1c, DRAM process and integrates logic chips in a 12-layer stacked structure. IMEC and Ghent University have successfully constructed a 120-layer alternating silicon and silicon-germanium structure on a 300mm wafer, laying the technical foundation for the development of high-density 3D DRAM.

1.2 Technological Breakthroughs Approaching Physical Limits

DRAM manufacturing requires precise control of charge for each storage unit at the nanoscale. Each storage cell usually consists of one transistor and one capacitor, which makes the manufacturing process extremely difficult. As Moore’s Law slows down, the industry is exploring new technologies such as 3D DRAM and 4F² DRAM.

The 4F² structure, as a key technical solution for verticalizing storage cells, reduces the area of a single storage cell by about one-third by transforming the traditional horizontal distribution of source, gate, and drain into a vertical layered structure.

Samsung is actively developing vertical channel transistor, or VCT, DRAM, while SK hynix is fully committed to promoting vertical gate, or VG, DRAM. SK hynix has stated that 4F² VG and 3D DRAM technologies will be applied to 10nm-and-below memory. Semiconductor equipment manufacturer Tokyo Electron estimates that DRAM using VCT and 4F² technologies will be available between 2027 and 2028.

1.3 Low-Power DRAM: The Battery-Life Guarantee for Edge AI

As generative AI migrates to edge devices, low-power DRAM becomes crucial. Micron’s innovation in low-power compression and discharge enables LPDDR5X to achieve a combination of high performance and low power consumption.

By redesigning the VDD2 rail into two domains, VDD2H and VDD2L, and using dynamic voltage and frequency switching control technology, the system can dynamically adjust voltage and frequency according to workload requirements.

By 2028, shipments of AI smartphones are expected to reach 912 million units, and smartphones supporting generative AI are expected to account for more than 54% of total smartphone shipments. All of these devices rely on the support of low-power DRAM.

2. Industrial Dimension: The Strategic High Ground Under Oligopoly

The DRAM industry is highly concentrated, with Samsung, SK hynix, and Micron forming the dominant global oligopoly. These companies are also the key engines driving upgrades across the semiconductor industry.

In the third quarter of 2025, the DRAM industry’s revenue reached USD 41.4 billion, an increase of 30.9% compared with the previous quarter. SK hynix maintained its top ranking with revenue of USD 13.75 billion and a market share of 33.2%. Samsung’s revenue was USD 13.5 billion, with a market share of 32.6%, maintaining second place. Micron’s revenue reached USD 10.65 billion, with a quarterly increase of 53.2%, and its market share rose significantly to 25.7%.

In the fourth quarter, Samsung’s revenue reached USD 19.3 billion, a quarterly increase of 43.0%, and its market share rebounded to 36.0%, returning it to the top position in the industry. SK hynix’s revenue was USD 17.22 billion, but its market share declined to 32.1%, ranking second.

According to Omdia data, Samsung Electronics’ sales in the fourth quarter of 2025 reached USD 19.156 billion, an increase of 40.6% compared with the previous quarter, while SK hynix recorded USD 17.226 billion.

In the key niche market of HBM, SK hynix held a market share of 60.8% in the third quarter, Samsung Electronics held 17.2%, and Micron Technology held 22%.

2.2 Extremely High Barriers to Entry

New players in the DRAM industry face extremely high technological, patent, manufacturing, and ecosystem barriers. The three major manufacturers have clearly stopped capital investment and technological iteration in DDR4 and plan to significantly reduce the proportion of DDR4 production capacity between 2025 and 2026.

This trend of industrial concentration, driven by both technology and capital, makes it almost impossible for latecomers to break the monopoly of the three giants in the short term.

2.3 DRAM as a Training Ground for Industrial Upgrading

DRAM is the best platform for polishing manufacturing processes and cultivating engineering talent. Mastering DRAM means obtaining a ticket to high-end chips such as CPUs and can strongly drive the upgrading of the entire supply chain, including lithography machines and high-purity materials.

From the rise of Japan’s semiconductor industry to the establishment of South Korea’s memory empire, DRAM has always been the core battlefield for industrial upgrading.

3. Economic Dimension: Igniting the Storage Super Cycle

DRAM is transitioning from a cyclical industry driven mainly by consumer electronics into an explosive growth market driven by AI computing power.

3.1 Massive Market Size

The global DRAM market is expected to reach USD 121.83 billion by 2025 and is projected to grow from USD 128.36 billion in 2026 to USD 223.7 billion in 2034, with a compound annual growth rate of 7.20% during the forecast period. The Asia-Pacific region is expected to dominate the global DRAM market by 2025, with a market share of 45.80%.

What is even more striking is the explosion of the overall memory market. According to TrendForce forecasts, the memory market is expected to grow from about USD 220 billion in 2025 to about USD 890 billion in 2026, an increase of about USD 670 billion. This increase alone surpasses the total size of individual markets such as smartphones, personal computers, or servers.

3.2 The Strongest Price Increase Cycle in History

DRAM prices are experiencing an unprecedented surge. Since July 2025, DRAM prices have continued to rise rapidly, with most categories seeing increases of more than 100%. PCPartPicker data shows that DDR4 and DDR5 prices have increased by two to three times within the past year. Entering 2026, the price increase has not slowed down; instead, the pace is accelerating.

Specifically, DRAM contract prices increased by approximately 4.5 times from the third quarter of 2025 to the second quarter of 2026. From the first quarter of 2025 to the second quarter of 2026, the cumulative increase in DRAM contract prices exceeded 300%.

The price of some scarce DDR4 specifications per unit rose from less than USD 3.2 at the beginning of 2025 to USD 64.5, an increase of up to 1,922.8%. According to Counterpoint data, DRAM contract prices increased by 40% to 50% quarter-on-quarter in the fourth quarter of 2025 and by 90% to 95% year-on-year in the first quarter of 2026, while HBM prices rose by more than 200%.

TrendForce predicts that DRAM prices will increase by more than 60% in the first quarter of 2026, with annual output value reaching USD 404.3 billion and annual growth reaching 144%. Taking 256GB DDR5 server memory as an example, the price of a single module has exceeded RMB 40,000. If 100 units are purchased at once and packed in one box, the value would be RMB 4 million, which is worth more than many properties in Shanghai.

3.3 The Deep Logic of Supply-Demand Imbalance

The root cause of this round of price increases lies in the combined effect of exploding AI demand and supply contraction. The DRAM demand of AI servers is 8 to 10 times that of regular servers. Servers are rapidly surpassing smartphones to become the largest demand market, and server DRAM is expected to account for more than 50% by 2026.

On the supply side, the three major manufacturers are shifting more than 70% of their production capacity toward HBM and DDR5. The proportion of HBM in total DRAM supply will increase from 7.9% in 2025 to 9.1% in 2026, corresponding to an annual growth rate of approximately 88%. The HBM production capacity of the three major manufacturers has been almost fully booked for the next year.

The global DRAM supply-demand ratio by 2025 is approximately +8%, meaning supply is slightly higher than demand and the market is in a loose equilibrium. In 2026, the global DRAM supply-demand ratio is expected to shift to -12%, indicating severe undersupply.

Samsung, SK hynix, and Kioxia have already sold out all their NAND production capacity for 2026 ahead of schedule and are in talks with large-scale cloud service providers regarding capacity allocation for 2027.

3.4 Cost Transmission to Downstream Industries

The sharp rise in DRAM prices is profoundly affecting downstream industries. The quarter-on-quarter increase in PC DRAM surged from 38% to 43% in the fourth quarter of 2025 to 105% to 110% in the first quarter of 2026, directly driving up the installation and upgrade costs of personal computers.

The quarter-on-quarter increase in server DRAM rose from 53% to 58% to 88% to 93%, sharply increasing procurement cost pressure for enterprise-level computing infrastructure.

Buyer Reminder:

For overseas distributors, OEMs, server integrators, and AI hardware buyers, early demand planning, locked supply agreements, alternative part-number mapping, and long-term allocation management are becoming essential in the DRAM procurement cycle.

4. Geopolitical Dimension: The Computing Chip in Great-Power Competition

DRAM has become a core battlefield in great-power technology competition. Its strategic significance is no less important than that of advanced-node logic chips.

4.1 U.S. Export Controls

In October 2022, the United States announced the inclusion of DRAM process equipment below 18 nanometers in export controls to China. The purpose was to prevent Chinese companies from purchasing equipment to expand production capacity and to restrict the development of DDR5 or higher-order DRAM products in China.

Subsequently, the United States further revoked VEU exemptions for companies such as Samsung and SK hynix in China. This means that their semiconductor production in Chinese factories will face stricter scrutiny.

The United States is shifting from temporary measures to stricter and more permanent policies to ensure that advanced semiconductor technology and equipment do not flow into China.

4.2 China’s Countermeasures and Responses

China has responded by imposing export restrictions on key materials such as rare earths and lithium batteries. The Chinese Ministry of Commerce has explicitly included rare earth items with the ultimate purpose of developing and producing logic chips of 14 nanometers or below, or memory chips of 256 layers or above, in export controls.

The AI reserve competition under great-power rivalry is reshaping the supply chain structure of the global memory industry.

4.3 Quasi Super Cycle and Strategic Autonomy

Due to ongoing geopolitical conflicts and the continued restructuring of the global supply chain, companies currently view the market as being in a quasi super cycle.

If HBM and DDR5 account for more than 50% of global DRAM revenue in the next three to five years, and if demand from AI, HPC, and automotive applications continues to rise, it cannot be ruled out that the DRAM industry will enter a true super cycle.

Without core DRAM technology, it is impossible to manufacture HBM, and the efficient operation of high-end intelligent computing centers cannot be discussed. This directly relates to national computing power security and strategic autonomy.

Fluctuations in DRAM will eventually spread to every corner of society, profoundly shaping people’s daily lives.

5.1 Quietly Supporting Daily Life

From smartphones and personal computers to cloud services, behind every click and search are countless DRAM chips instantly reading and writing massive amounts of data.

As the Chairman of Micron has stated, artificial intelligence is changing how the world enriches lives with information, and hardware, including Micron’s DRAM and NAND flash technologies, is an indispensable disruptive force.

We are already living in an AI-driven world. Facial recognition, real-time translation, and ubiquitous virtual assistants are no longer new technologies. The responsiveness of these systems depends on whether memory performance can match the processing power of processors. DRAM is the cornerstone of a smooth user experience.

5.2 Profound Changes in the Consumer Electronics Market

The shift in production capacity toward HBM has led to tight supply of DRAM for PCs and smartphones. Micron announced that it will stop selling Crucial consumer-grade products by the end of February 2026. Samsung has raised the contract prices of mobile DRAM products such as LPDDR4X and LPDDR5/5X by 15% to 30%.

These changes are reshaping consumer choices. Some mid-range smartphones are being forced to cancel high-capacity versions, while PC installation and upgrade costs have increased significantly.

5.3 Cost Driver of AI Applications

The cost of DRAM will ultimately be passed on to the price of AI services. More than 50% of the cost of an NVIDIA H100 GPU is attributed to HBM.

The high cost of memory means more expensive AI training, more expensive cloud inference, and more expensive edge AI devices. DRAM is becoming a key variable determining the democratization process of AI.

Conclusion

The history of DRAM evolution is also the history of modern information technology. DRAM evolved from a laboratory invention into the cornerstone of computing power driving the digital economy and a strategic resource in national competition.

From the bandwidth revolution of HBM to the structural breakthrough of 3D DRAM, from the strongest price increase cycle in history to geopolitical strategic struggles, DRAM is profoundly changing the world across five dimensions: technology, industry, economy, geopolitics, and society.

Today, we are standing at the starting point of a storage super cycle driven by AI demand. In the future, with breakthroughs in new technologies such as 3D DRAM, DRAM will continue to play a key role. It is not only the memory of computers, but also the bridge for humanity to reach an intelligent future.

Understanding DRAM means understanding one of the most profound technological and social transformations of our time.
