Memory makers prioritize HBM, advanced 3D NAND - Communications Today

As semiconductor industry competition intensifies, memory manufacturers are focusing on high-bandwidth memory (HBM) and advanced 3D NAND technologies to maintain competitive advantage. HBM technology ... Read original →

Memory makers' pivot to HBM and advanced 3D NAND is a reactive move to the AI compute arms race. Technically, HBM strains TSV, hybrid bonding, and CoWoS packaging capacity—effectively creating a duopoly among TSMC, Samsung, and SK Hynix—while 3D NAND scaling beyond 200 layers spikes demand for etch and deposition tools, inflating capex. Compliance-wise, U.S. export controls force Taiwan, China and mainland Chinese firms to accelerate domestic material and equipment validation, but extended yield ramp timelines will pressure near-term margins. In market positioning, Micron leverages HBM3E into NVIDIA’s supply chain, Samsung locks cloud providers with QLC 3D NAND, while YMTC risks exclusion from premium segments if equipment bans persist. Over the next 12–24 months, HBM adoption will expand from AI training to autonomous driving and edge inference, and falling 3D NAND costs will trigger enterprise SSD refresh cycles—yet overcapacity risks are quietly building ahead of an expected glut by Q1 2027.
