Samsung Electronics and SK Hynix are pushing forward their production schedules for sixth-generation high-bandwidth memory to February 2026. Industry sources and South Korean media reports confirm the accelerated timeline. The two companies aim to begin volume manufacturing of HBM4 months earlier than previously anticipated. The goal is to meet surging demand for artificial intelligence infrastructure. By accelerating their timelines, the South Korean chipmakers seek to solidify their dominance in the AI memory market before global competitors can scale similar technologies.
