AI的Memory时刻4：AIDRAM需求旺盛，行业供需紧张有望延续

Investment Rating - The report provides a "Buy" rating for the industry, indicating an expectation of stock performance exceeding the market by more than 10% over the next 12 months [29]. Core Insights - The demand for AI DRAM is robust, and the supply-demand tension in the industry is expected to continue [2]. - AI memory is becoming a foundational capability that supports contextual continuity, personalization, and historical information reuse, which is likely to accelerate the deployment of AI applications [23]. - The value of AI memory is shifting from being a cost item to an asset item, enhancing the importance of related upstream infrastructure [23]. Summary by Sections 1. Single GPU Corresponding DRAM Storage Capacity and Production Capacity Continuously Increasing - The capacity of DRAM associated with single GPUs is significantly increasing, with specific models showing HBM capacities of 192GB, 288GB, and up to 1024GB, while CPU DRAM capacities range from 242GB to 1536GB [11][12]. - The production capacity for HBM is approximately three times that of traditional CPU DRAM, leading to substantial increases in equivalent DRAM production capacity for various GPU models [11][12]. 2. New Production Capacity Release Pace is Slow, Short-term Demand Growth Cannot Be Matched - AI server DRAM is the largest incremental application segment, with a projected demand growth rate of 26% in 2026 due to accelerated AI server deployments [19]. - Capital expenditure in the DRAM industry is expected to rise from $53.7 billion in 2025 to $61.3 billion in 2026, but new production capacity will primarily be released in 2027 and beyond [19]. - A structural mismatch is anticipated in 2026, with rapidly increasing demand and slow supply release, leading to a continued tight supply situation driven by AI [19]. 3. Investment Recommendations - The report suggests focusing on core beneficiaries within the industry chain, as AI memory is expected to drive significant advancements in AI applications [23].
