As artificial intelligence and high-performance computing continue to advance rapidly, high-bandwidth memory (HBM) paired with GPUs has become a critical battleground in the semiconductor industry. Joungho Kim, a professor of electrical engineering at KAIST and widely recognized as the “father of HBM” in South Korea, emphasized the importance of emerging technologies such as hybrid bonding, high-bandwidth flash (HBF), and compute-in-HBM in shaping the future of memory design.
