存储芯片急单涌现，3D NAND代工“风口”属于谁？

Group 1 - The AI-driven infrastructure, including servers, data centers, and storage, is expected to grow from $149 billion in 2024 to $340 billion by 2030, making it the fastest-growing segment in the semiconductor market [1] - The demand for storage chips is increasing due to the AI wave, prompting major storage manufacturers like Samsung and SK Hynix to shift some DRAM capacity to HBM and focus NAND production on high-layer, high-performance products [1] - The shift in production strategies has created a supply gap in the storage market, leading to a "super cycle" for storage chips starting in 2025, with expectations of ongoing shortages in the coming years [1][2] Group 2 - The market for 3D NAND foundry services is projected to be around $10 billion, with significant demand for mid-to-low layer 3D NAND chips to meet the needs of various applications, including AR glasses [2] - The current supply-demand mismatch has resulted in urgent orders for storage solutions, as major suppliers are exiting fragmented markets, creating opportunities for smaller suppliers [3] - The domestic market is poised for growth in 3D NAND foundry services, leveraging existing logic chip production lines to enhance capacity utilization [3][4] Group 3 - The Jiangsu and Yangtze River Delta regions are experiencing strong demand for storage chips driven by industries such as smart terminals, new energy vehicles, and AI, facilitating stable order acquisition for foundry services [4][5] - Jiangsu has developed a dense integrated circuit industry cluster, with companies like Huazhong Microelectronics and Changjiang Electronics Technology contributing to a complete storage industry chain [5] - The region is positioned to become a strategic node in the global storage industry chain, supported by a combination of IDM manufacturing bases and foundry services [5]
