闪存芯片，越来越缺

Core Viewpoint - The DRAM and flash memory markets are experiencing significant volatility, with prices recently surging due to demand from AI data centers, despite a previous downturn caused by oversupply and reduced IT demand [2]. Group 1: DRAM Market Insights - Over half of global servers require hundreds of GB of HBM stacked memory, which consumes multiple DRAM chips, leading to production challenges and low yields [3]. - The DRAM shortage is exacerbated by the high demand for HBM, which diverts chips away from high-performance DDR5 memory production [3]. Group 2: Flash Memory Market Dynamics - The flash memory market is recovering from a severe downturn in 2023, with significant demand expected to drive revenue growth for manufacturers like Solidigm in 2024 and beyond [4][5]. - Flash memory prices have increased by 50% to 70% due to demand exceeding supply, particularly for applications in AI supercomputers [5]. Group 3: AI Supercomputer Storage Architecture - NVIDIA's AI supercomputer architecture includes a four-layer storage system, with HBM and DRAM playing critical roles in processing large datasets [6]. - The architecture emphasizes the importance of regular checkpoint maintenance to prevent data loss during computations, highlighting the need for substantial flash storage [6]. Group 4: Future Demand Projections - For a 1 Gbps system using NVIDIA GPUs, the estimated internal flash storage requirement is 8.5 exabytes, with an additional 16.5 exabytes needed for external network storage, totaling 25 exabytes [8]. - The demand for flash memory is projected to grow significantly, with estimates of 135 exabytes consumed in 2023, 315 exabytes in 2024, and 450 exabytes in 2025, indicating a substantial market opportunity for manufacturers [8][9].
