Core Viewpoint - The article discusses the current trends and forecasts in the memory market, particularly focusing on NAND and DRAM, highlighting the demand dynamics and inventory levels of major players like Samsung and SK Hynix [1][2][3]. Summary by Sections Market Overview - The article references UBS research, indicating that Samsung and SK Hynix expect a modest increase in DRAM shipments for Q2 2025, with Samsung projecting less than 10% growth and SK Hynix over 20% for NAND [2]. - UBS has adjusted its NAND price forecast for Q2 from +5% to +3%, citing resistance from customers against rising SSD prices [2]. Demand and Inventory - As of Q1 2025, DRAM inventory levels are decreasing faster than expected, with smartphone customers holding about 10 weeks of inventory and PC manufacturers around 12 weeks [3]. - For NAND, smartphone manufacturers have approximately 9 weeks of inventory, while SSD inventory stands at 11 weeks [3]. HBM Demand Forecast - UBS has revised its HBM demand forecast for 2025 down from 203 billion Gb to 189 billion Gb, reflecting a year-on-year growth of 105%, and for 2026 from 303 billion Gb to 291 billion Gb, with a growth rate of 54% [3][24]. - The demand for ASICs is expected to outpace GPUs, with ASICs accounting for 54% of total HBM demand by 2026, up from 41% in 2025 [3]. Supplier Insights - Samsung's HBM bit shipments are projected to increase from 5.1 billion Gb in 2024 to 11.2 billion Gb by 2026, representing 8.1% of its total DRAM bits [9]. - SK Hynix is expected to grow its HBM shipments from 6.8 billion Gb in 2024 to 17.4 billion Gb by 2026, which will account for 17% of its total DRAM bits [9]. Production Capacity - Longxin's wafer production capacity is expected to reach 170,000 wafers per month by the end of 2024, with plans to increase to 230,000 wafers per month by the end of 2025 [24]. - Yangtze Memory Technologies Company (YMTC) is also expanding its production capacity, aiming for 160-layer technology despite facing challenges due to U.S. restrictions [25]. Competitive Landscape - The article highlights the competitive dynamics among major players, with Samsung and SK Hynix leading in HBM production, while Micron is also increasing its HBM output significantly [9][24]. - The market share of DRAM suppliers is detailed, showing Samsung at 39.5%, SK Hynix at 28.9%, and Micron at 22.9% for 2025 [27]. Future Outlook - The article concludes with a cautious outlook for the memory market, emphasizing the uncertainty due to tariff issues and potential specification downgrades in NAND demand [2][24].
