Core Viewpoint - Samsung Electronics faces increasing pressure to revitalize its competitiveness in the memory chip market, particularly in high bandwidth memory (HBM), which is crucial for advanced AI computing. Establishing a supply agreement with major buyer Nvidia is essential for Samsung [1][2]. Group 1: HBM Market Dynamics - SK Hynix has dominated the HBM market since 2022, supplying Nvidia exclusively with HBM3, while Samsung has not yet passed Nvidia's stringent certification tests. Analysts predict that by 2025, SK Hynix will hold a 57% market share, followed by Samsung at 24% and Micron at 19% [1]. - Samsung's relative weakness in HBM is a key factor in its declining position in the broader DRAM market, where it lost its leadership to SK Hynix for the first time, with market shares of 34% and 36% respectively [2]. - Samsung is focusing on improving its HBM products and aims to pass Nvidia's certification for HBM3E chips, which could open doors for future orders [2]. Group 2: Semiconductor Business Performance - Samsung's foundry division has secured a significant order from Tesla for next-generation AI chips, which may help offset substantial losses in its memory division [3][4]. - The foundry's 2nm process is reportedly achieving expected yields and production stability, with plans for mass production by the end of the year [4]. - The contract with Tesla is seen as a critical achievement, potentially leading to more orders from other major tech companies and improving Samsung's competitive position against TSMC [5]. Group 3: Future Strategies and Expectations - Samsung plans to implement a dual-track strategy to enhance its existing mature process business while accelerating its pursuit of TSMC [6]. - The foundry's strong performance is expected to positively impact Samsung's overall semiconductor results and help restore its memory competitiveness [6]. - Samsung is working on the next generation of HBM (HBM4) and has submitted its sixth-generation DRAM (D1c) for validation, with production expected to ramp up soon [7].
