The U.S.-Iran détente, though a short-term geopolitical shift, unlocked pent-up valuation in the memory sector. Technically, stabilized DRAM/NAND pricing combined with AI server demand for HBM3e/HBM4 is forcing Samsung and SK Hynix to accelerate EUV layer scaling, while Micron’s 1-beta node yield advantage secures NVIDIA GB200 orders—creating a tech-capacity flywheel. On compliance, Western Digital’s post-SanDisk focus on enterprise SSDs sidesteps secondary Iran sanctions, but fabs in Taiwan, China and Korea still face rising costs from U.S. CHIPS Act export controls. Strategically, Samsung may undercut PC DRAM prices to regain share, while YMTC’s potential equipment access could disrupt NAND pricing. Over the next 18 months, AI memory capex will pivot toward CoWoS-R and 3D TSV packaging; legacy HDD players like Seagate must pivot to edge-AI storage or risk irrelevance.
