Micron Builds AI Data Center Push

Micron used COMPUTEX 2026 to present a broad memory and storage portfolio for artificial intelligence infrastructure. The company positioned its products across training, inference, agent-based systems, and long-context workloads. Besides, the update showed how memory bandwidth and storage speed now shape AI system performance.

The company said AI context lengths continue to grow sharply each year. It also noted that memory content per server doubled over the past three years. Micron framed memory and storage as core assets in AI data centers.

Micron’s data center lineup covers HBM, LPDDR, DDR, RDIMMs, and enterprise SSDs. HBM supports fast model execution and hot key-value cache, while DDR supports orchestration and larger contexts. Meanwhile, SSDs handle persistent cache needs and large data lakes across AI infrastructure.

HBM4 and RDIMMs Strengthen MU’s AI Case

Micron highlighted the HBM4 36GB 12H as a key product for large-language-model inference. The company said the product can raise inference throughput by 2.6 times. Moreover, that gain comes for every two-times increase in bandwidth, based on its testing.

The company also pointed to SOCAMM2 as part of its low-power data center strategy. Micron said its 256GB SOCAMM2 offers the highest capacity in that class. Besides, it uses one-third the power and one-third the footprint of standard RDIMMs.

Micron also sampled a 256GB DDR5 RDIMM built on 1-gamma technology. The module can reach speeds of up to 9,200 megatransfers per second. Additionally, it runs 40% faster than current volume modules and cuts operating power by over 40%.

SSD and Edge AI Products Expand Growth Base

Micron also promoted its data center SSD portfolio for AI training and inference workloads. The Micron 9650 SSD became the first commercially available PCIe Gen6 SSD, according to the company. Meanwhile, the 6600 ION now reaches 245TB and targets high-density storage needs.

The company said the 6600 ION reduces rack footprint by 82% versus HDD deployments. It also cuts power use by half compared with hard-drive-based systems. Micron linked its SSD roadmap to lower data center space and energy costs.

Micron also extended its AI focus to PCs, phones, vehicles, robotics, and embedded systems. Its LPCAMM2, GDDR7, LPDDR5X, 4600 SSD, and UFS 4.1 target faster edge processing. Overall, the COMPUTEX update placed MU stock within the growing link between AI compute and memory demand.
