Samsung Electronics is cutting production of mature-node DDR4 memory and reportedly scaling back its third-generation high-bandwidth memory (HBM2E) business to focus resources on fifth-generation (HBM3E) and sixth-generation (HBM4) products. According to Chosunbiz, Samsung is reducing HBM2E output and aiming to pass Nvidia’s HBM3E certification to boost production, while also targeting early leadership in the emerging HBM4 market.
