Micron Begins Shipping HBM4 Memory: A Leap Forward for AI and High-Performance Computing

HBM4 Memory by Micron: 36GB Capacity and 2TB/s Bandwidth Samples Shipping Soon

Micron is preparing to ship early samples of its new HBM4 memory modules, which stack 12 DRAM dies to offer 36 GB of capacity per module. These engineering samples will be sent to select partners soon, with mass production expected to start in early 2026. The HBM4 modules are built on Micron's 1β process, a DRAM manufacturing technology that's been in use since 2022. Later this year, Micron plans to introduce an EUV-enhanced 1γ process for DDR5 memory, but HBM4 currently relies on the established 1β node. One of the main improvements with HBM4 is the wider memory interface. The interface width doubles from 1,024 bits per stack in previous generations to 2,048 bits, allowing the modules to deliver a sustained bandwidth of 2 terabytes per second. This translates to roughly a 20% efficiency increase over the current HBM3E memory standard. The increased number of stacked dies combined with this wider interface makes data movement more efficient, which is especially important for multi-chip configurations and setups requiring memory-coherent interconnects. NVIDIA and AMD are expected to be the first companies to adopt HBM4 memory in their products. NVIDIA plans to use the modules in its Rubin-Vera AI accelerators, which are set to launch in the second half of 2026. Meanwhile, AMD will likely integrate HBM4 into its next-generation Instinct MI400 series, with more information anticipated at their Advancing AI 2025 conference. The added memory capacity and bandwidth of HBM4 address the increasing performance needs of generative AI, high-performance computing, and other data-heavy applications. As Micron moves towards large-scale production, the company will face challenges around thermal management and proving real-world performance. Thermal performance is critical since higher stack counts and increased bandwidth can generate more heat. Real-world benchmarks will also be essential to demonstrate how effectively HBM4 supports demanding AI workloads and HPC tasks. Source: Micron
