In the fourth quarter of 2025, the global DRAM memory market witnessed substantial growth, with its size soaring to USD 52.47 billion, marking a quarter-on-quarter surge of approximately 30%. Within this thriving market, Samsung Electronics emerged as a standout performer, with its sales share climbing to 36.6%, translating to sales of USD 19.156 billion. This represents a remarkable quarter-on-quarter increase of 40.6%. Meanwhile, SK Hynix also secured a significant market presence, accounting for 32.9% of the market share, with sales reaching USD 17.226 billion, up by 25.2% from the previous quarter. In contrast, Micron experienced a decline in its market share, which dropped from 25.8% in the third quarter to 22.9%.

Notably, after relinquishing its title as the 'largest DRAM manufacturer' in the first quarter of 2025, Samsung Electronics made a swift and impressive comeback, reclaiming the top position within a mere year. This achievement underscores Samsung's resilience and competitiveness in the fiercely contested DRAM market.
