SK hynix has completed the development of HBM4 memory chips, which are now ready for mass production, six months after the Korean chipmaker delivered samples of its 12-layer HBM4 to key customers, including Nvidia. SK hynix calls the launch of the first HBM4 device a symbolic turning point beyond artificial intelligence (AI) infrastructure limitations.
Nvidia CEO Jensen Huang had asked SK hynix to supply 12-layer HBM4 chips six months earlier than its original launch schedule, which was set for early 2026. As a result, the Korean chipmaker moved the goalpost of HBM4 mass production to the second half of 2025.
