DRAM，生变

Core Viewpoint - The storage market is undergoing significant changes, with HBM technology becoming a strategic focal point for leading companies like SK Hynix, Samsung, and Micron, as they compete for future revenue growth [3][4][18]. Group 1: DRAM Market Dynamics - SK Hynix has maintained its position as the global leader in the DRAM market, increasing its market share from 36.9% in Q1 to 39.5% in Q2, while Samsung's share decreased from 34.4% to 33.3% [2]. - In terms of revenue, SK Hynix reported $12.226 billion in Q2, surpassing Samsung's $10.3 billion by over $1.9 billion, marking a significant shift in the competitive landscape [2]. - The ongoing transition in the DRAM market is characterized by a focus on HBM technology, which is expected to drive future growth [3][10]. Group 2: HBM Technology and Customization - HBM has evolved into a critical component for high-performance AI chips, with SK Hynix and Micron entering the final testing phase for the sixth generation of HBM (HBM4), set to supply NVIDIA [3][4]. - SK Hynix is positioned as the primary supplier for NVIDIA's HBM4, with expectations to finalize supply contracts by September [4]. - Customization of HBM products is becoming increasingly important, with SK Hynix already engaging with major clients like NVIDIA and Microsoft to develop tailored solutions [5][6]. Group 3: DDR4 Market Resurgence - The unexpected resurgence of DDR4 memory prices is attributed to supply shortages following announcements from major manufacturers to halt production by the end of 2025 [7][8]. - Current market prices for DDR4 have surged, with the average spot price for DDR4 16Gb reaching $16, significantly higher than DDR5 prices [7]. - Both Samsung and SK Hynix are reconsidering their plans to phase out DDR4, extending production timelines due to the profitability of older chips [8]. Group 4: Equipment and Technological Advancements - The introduction of High NA EUV equipment by SK Hynix is set to enhance DRAM production capabilities, allowing for finer circuit patterns and increased integration [13][14]. - The competition in the semiconductor equipment sector is intensifying, particularly with the development of hybrid bonding technology, which promises to improve performance and efficiency in HBM production [14][15]. - Companies like BESI and Applied Materials are leading the charge in hybrid bonding technology, which is expected to reshape the semiconductor equipment landscape [15][16]. Group 5: Future Outlook - The competition in the DRAM market is expected to escalate, particularly as companies adapt to the evolving demands of the AI era [18]. - The integration of various technologies and collaborative efforts among industry players will be crucial for success in the increasingly complex semiconductor ecosystem [18].
