SK Hynix Yonhap News

On the morning of the 23rd, SK Hynix announced after the Q4 earnings presentation, "We will apply the 1c nano process, which demonstrates excellent performance and stable initial yield, to HBM4E in the future to develop and supply next-generation HBM on schedule and maintain market leadership."

Regarding the 1c nano product, they stated, "During the development phase, the initial mass production target yield has been exceeded, and meaningful cost reductions are expected as mass production expands. Mass production will begin in the second half of the year with general DRAM applications, but a significant portion of this year's investment is already focused on HBM with secured customer demand and infrastructure investment. We will consider ramp-up investments in the future based on demand." They also explained, "Building on the excellent development experience of the 1b nano, the 1c nano product development was completed in the second half of last year, securing mass production capability. The 1c nano-based DDR5 product supports a maximum speed 28% higher than the previous product and improves power efficiency by more than 9%. As we enter the AI era, this product is optimized for future server demand, matching the trends of fast data processing speeds and low power consumption."
