Core Insights - The memory "super cycle" driven by artificial intelligence (AI) is accelerating, leading major global suppliers to significantly raise prices and prompting customers to secure long-term supply contracts to mitigate increasing shortage risks [1][2] Group 1: Price Increases and Supply Contracts - Samsung Electronics and SK Hynix have raised prices for DRAM and NAND flash by up to 30% in Q4, reflecting a direct response to the current supply-demand imbalance [1] - Major clients, including U.S. electronics companies and data center operators, are negotiating long-term supply contracts of 2 to 3 years with Samsung and SK Hynix to ensure supply stability amid growing concerns over shortages [2] Group 2: Supply Shortages and Market Dynamics - The AI-driven supply shortage is expected to last longer and be more intense than previous cycles, with analysts predicting a duration of three to four years due to factors such as significant new investments in AI servers and ongoing memory upgrades in general servers [1][3] - The shift in procurement strategies is evident as companies are moving from flexible quarterly or annual DRAM contracts to securing additional supply in advance due to anticipated shortages [2] Group 3: Demand Drivers - The current memory super cycle is characterized by broad-based demand growth, driven by substantial investments in AI servers, memory upgrades for general servers to support AI applications, and the proliferation of "edge AI" features in smartphones and PCs [3] - As AI investment shifts focus from large-scale data training to inference applications, the demand for general DRAM is rising, exacerbating the supply-demand imbalance in the DRAM market [3]

Core Viewpoint - The article discusses the impact of AI large language models, particularly GPT-5, on the demand for memory components such as HBM, DRAM, and NAND, suggesting a potential memory supercycle driven by AI inference workloads [4][8]. Memory Demand Analysis - The demand for HBM and DRAM is primarily driven by the inference phase of AI models, with GPT-5 estimated to require approximately 26.8 PB of HBM and 9.1 EB of DRAM if a 50% cache hit rate is assumed [8][10]. - NAND demand is significantly influenced by retrieval-augmented generation (RAG) processes, with an estimated requirement of 200 EB by 2025, considering data center capacity adjustments [8][11]. Supply and Demand Dynamics - The global supply forecast for DRAM and NAND indicates that by 2025, the supply will be 36.5 EB and 925 EB respectively, with GPT-5's demand accounting for 25% and 22% of the total supply [9]. - The article highlights a shift from oversupply to a shortage in the NAND market due to increased orders from cloud service providers, leading to price increases expected in late 2025 and early 2026 [11][12]. Beneficiary Companies - Companies such as KIOXIA and SanDisk are identified as key beneficiaries of the NAND price increases, with KIOXIA having the highest price elasticity but facing debt risks, while SanDisk is expanding its enterprise segment [12]. - Major manufacturers like Samsung and SK Hynix are positioned to benefit from both HBM and NAND markets, although their valuations may already reflect some of the positive outlook [12]. Market Outlook - Analysts predict that the current cycle is in its early stages, with profitability expected to begin in Q4 2025 and a potential explosion in demand in 2026, particularly for companies like SanDisk [13]. - The article notes several risk factors that could impact the sustainability of this cycle, including potential overestimation of cloud orders and the possibility of increased NAND production leading to oversupply by 2027 [13].
