High-bandwidth memory (HBM) is a modern form of DRAM that stacks chips and uses wide connections to achieve very high data rates. Because it is compact and energy-efficient, it handles large datasets well.
Industries such as artificial intelligence, gaming, data centers, and advanced graphics use HBM to achieve faster computing, improved performance, and lower power consumption. This article highlights the main companies driving HBM technology around the world.
The Big Three HBM Manufacturers
The following are the top three high-bandwidth memory companies, often known as the Big Three.
- SK Hynix
Based in South Korea, SK Hynix leads the global HBM market and is expected to retain over 50% of the market share, which stood at 62% in Q2 2025
SK Hynix became a leader by starting early with stacked DRAM design and building a strong partnership with Nvidia, which uses SK Hynix’s HBM3E and HBM4 memory in its AI accelerators.
In early 2025, SK Hynix completed the world’s first 12-layer HBM4 samples and plans to begin mass production later that year. HBM4 offers over 2 TB of bandwidth and employs advanced techniques such as MR/MUF to enhance cooling and stability.
With HBM demand expected to grow by about 30% each year until 2030, SK Hynix is investing heavily in new memory factories and research to maintain its market leadership.
- Micron Technology
Micron Technology, based in the United States, entered the HBM market after its Korean competitors, but has quickly caught up. By Q2 2025, Micron’s market share reached 21%, putting it ahead of Samsung Electronics and demonstrating its growing influence in the industry. Micron sent HBM4 36 GB 12HI samples to key customers for next-generation AI platforms. Made with its advanced 1b DRAM process, HBM4 has a 2048-bit inference interface, data rates over 2 TB, and is more than 20% more power-efficient than HBM3e.
Micron also provides HBM3E12 high memory for NVIDIA’s Blackwell and AMD’s MI350 platforms. The company plans to boost HBM4 production in 2026 to support its customers’ new AI system launches.
- Samsung Electronics
Samsung Electronics remains a major player in the HBM industry, using its large manufacturing capacity and advanced processes to stay competitive. In Q2 2025, Samsung held 17% of the HBM market.
Although Samsung dropped to third place in Q2 2025, it is using its manufacturing strengths to try to catch up. At SEDEX 2025, Samsung presented its sixth-generation HBM (HBM4) products, highlighting their high speed.
With HBM4 rolling out on a large scale, analysts believe Samsung’s market share could rise to over 30% by 2026.
Leading Companies Using HBM Technology.
Here are some top companies making the most of HBM technology.
- Advanced Micro Devices (AMD)
Advanced Micro Devices (AMD) has quickly adopted new memory technologies to improve computing efficiency. It was one of the first to use HBM in mainstream products, starting with early Radeon graphics cards, and continues to improve stacked memory in its latest data center solutions.
AMD’s Instinct MI300 accelerator family demonstrates the importance of HBM for high-performance computing. The MI300A model combines CPU and GPU cores in a single package, with 128 GB of HBM3 memory and a peak bandwidth of 5.3 TB.
The MI300X, designed for AI and high-performance computing, increases memory to 122 GB of HBM3, making it one of the largest memory setups in the industry today.
- NVIDIA Corporation
NVIDIA is central to global HBM demand because its AI accelerators require substantial memory bandwidth to run thousands of GPU cores simultaneously. The company uses HBM3 and HBM3E technologies to meet these needs.
The NVIDIA H100 Tensor Core GPU, widely used in AI and cloud systems, uses HBM3 stacks. The newer H200 adds HBM3E for even faster data. SK Hynix mainly supplies these memory stacks for NVIDIA, and Samsung Electronics is expected to provide more as production grows.
- Intel Corporation
Intel’s use of HBM shows how important memory bandwidth is for different types of computing. Instead of relying solely on parallel processing like GPUs, Intel combines x86 CPUs, Xe GPUs, and AI accelerators, all of which benefit from faster on-package memory.
The HBM Future and Market Trends
The HBM market is evolving quickly as technology advances. These changes are pushing high-bandwidth memory companies to explore new opportunities. Here’s what’s happening:
- HBM4 and beyond: high bandwidth memory has entered a new phase. In April 2025, JEDEC released the HBM4 standard, which features a 2048-bit interface and transfer speeds of almost two TBs per stack. HBM4 doubles the throughput of HBM3E and offers better energy efficiency and scalability for AI and data centers.
- Continued expansive demand drivers: HBM is now used beyond just GPUs. It’s being adopted in AI accelerators, ASICs, and high-performance CPUs, all of which require fast, low-latency data handling. Analysts expect HBM shipments to exceed 30 billion gigabytes in 2026, driven by growth in AI infrastructure projects.
- Market outlook: The future looks bright for the HBM industry. SK Hynix predicts a strong 30% annual growth rate through 2030, and the HBM market reaching several billion dollars as demand for AI training and inference grows.
HBM’s future is tied to the fast progress of AI data center technology and new packaging methods.
