Micron Launches HBM4 36GB Modules and Industry-First PCIe Gen6 SSD
Micron has begun Q1 volume shipment of its HBM4 36GB 12H modules delivering over 2.8 TB/s bandwidth and 20% improved power efficiency compared to HBM3E. The company also ramped industry’s first PCIe Gen6 data center SSD and 192GB SOCAMM2 modules for AI workloads.
1. Micron Begins Volume Shipment of HBM4 36GB 12H
Micron began volume shipments of its HBM4 36GB 12H modules in Q1 2026, achieving over 11 Gb/s pin speeds that translate to more than 2.8 TB/s bandwidth and a 20% power efficiency gain relative to its HBM3E products. These modules are designed for NVIDIA Vera Rubin platforms.
2. Advanced HBM4 Packaging Demonstrates 48GB 16H
The company has demonstrated advanced packaging by stacking 16 HBM4 die to create 48GB 16H samples, offering a 33% capacity increase per placement compared to the 36GB 12H variant, signalling potential for future higher-capacity memory cubes.
3. Industry-First PCIe Gen6 SSD Hits High-Volume Production
Micron’s 9650 data center SSD, the industry’s first PCIe Gen6 drive in high-volume production, delivers up to twice the read performance of Gen5 at 100% higher performance per watt, achieving 28 GB/s sequential read throughput and 5.5 million random read IOPS for AI workloads on NVIDIA BlueField-4 STX.
4. High-Capacity SOCAMM2 Modules Expand AI Memory Portfolio
The company also ramped production of 192GB SOCAMM2 modules, expanding its low-power, high-capacity memory offerings for AI and HPC workloads on NVIDIA Vera Rubin NVL72 systems and standalone CPU platforms, rounding out a broad AI-optimized memory portfolio.
