Core Viewpoint - The memory chip market is shifting towards a more customized product approach, focusing on a few core customers and integrating them into an ecosystem [1][2]. Group 1: Market Trends - AI memory chips are becoming more specialized and reliant on a limited number of "locked-in" core customers [1]. - SK Hynix has benefited from the AI boom and is now a major supplier of NVIDIA's high-bandwidth memory (HBM) chips, with the latest HBM4e expected to be used in NVIDIA products starting in 2026 [1]. Group 2: Business Strategy - The new business model emphasizes deep collaboration with specific customers from the initial product development stage, allowing for higher customization flexibility in HBM4e compared to traditional HBM chips [2]. - There is a potential risk in this strategy as it increases dependency on AI clients like NVIDIA; if these clients experience slow growth, SK Hynix may also face a slowdown [2]. - Ensuring that selected customers become leaders in their respective fields is crucial for the success of this new model [2].
