In the HBM memory market, Samsung once lagged behind SK Hynix and Micron, becoming the third manufacturer to achieve mass production. However, Samsung is determined to succeed in HBM4 technology. Recently, it was reported that Samsung's HBM3E has finally obtained certification from NVIDIA 18 months after mass production. Previously, Samsung's HBM3E had already been recognized by AMD, and now Samsung is qualified to supply to these two giants.
