【Midday Depth|The Year of HBM4 Mass Production】
Micron dropped 9 AI storage products at COMPUTEX 2026, with the main highlight being HBM4:
• Bus width doubled from 1024bit to 2048bit
• Single stack bandwidth exceeds 2.8TB/s, more than double that of HBM3E
• Channel count increased from 16 to 32, with 36GB per module
The oligopoly remains, but competition is ramping up. Recent spot demand for DDR5 has strengthened due to brand needs, and NAND contract prices have surged beyond expectations. Storage is shifting from "cyclical fluctuations" to "AI essential pricing".
Interesting data: HBM sells for $15-20 per GB, while regular DRAM is only $2-3. In the storage game, AI scenarios command an 8x premium. Whoever can secure HBM capacity holds the ticket to the next generation of computing power.
