SK hynix Reportedly Ramping Up 1c DRAM Share Significantly, with First Application in HBM4E

According to industry sources cited by Korea's ChosunBiz, Sthe share of 1c DRAM at SK hynix expanded from around 10% in the first quarter this year to the 13% range in the second quarter. It is forecast to rise to the 24% range in the third quarter and the 34% range in the fourth quarter. In the first quarter of next year, the 1c share is expected to climb into the 35% range, surpassing 1b (33% range) for the first time to become the main process. Furthermore, unlike Samsung, which plans to adopt 1c DRAM starting from HBM4, SK hynix chose a strategy prioritizing mass-production stability with proven 1b DRAM and advanced MR-MUF packaging technology, and first applied 1c DRAM as the core HBM chip starting with HBM4E.
