Overview

Samsung Electronics is a South Korean multinational and one of the world’s largest semiconductor manufacturers. Together with SK Hynix, Samsung accounts for roughly 70% of global DRAM supply and a commanding share of high-bandwidth memory (HBM) used in AI accelerators.

Key Facts

Newsletter Relevance

Samsung’s dominance in memory chips places it at the center of several newsletter themes: Infrastructure Warfare (helium supply disruptions cascade into AI chip production), Chokepoint Control (concentration of critical manufacturing), and the AI buildout (HBM is the gating component for AI accelerators).
