Samsung Electronics has achieved a major milestone in its development of next-generation high-bandwidth memory (HBM4) technology. The production yield for its HBM4 chips has surged to nearly 80%, reaching the semiconductor industry's esteemed "golden yield" benchmark. This accomplishment has significantly enhanced market trust in Samsung's proficiency in this arena, providing a robust platform for its resurgence in the "AI DRAM" market, which is currently led by SK Hynix.
