Samsung, SK Hynix Unveil Next-Gen Memory in US, Eyeing Continued Global Leadership

South Korean semiconductor giants Samsung Electronics and SK Hynix are intensifying their global competition by unveiling cutting-edge memory products and technologies. Both companies are making significant investments to maintain South Korea's leadership in the worldwide memory market, a position expected to hold until at least 2031.

At the "Future of Memory and Storage (FMS) 2026" event in Santa Clara, California, Samsung Electronics debuted next-generation memory prototypes featuring novel design architectures. Among these was the "zHBM" (zero-latency High Bandwidth Memory), which vertically stacks memory chips atop AI accelerator chips (xPUs). Samsung claims this design minimizes data transfer distances, significantly boosting performance and power efficiency compared to the 8th generation HBM (HBM5), potentially achieving up to eight times higher performance.

Samsung also showcased its "zNAND-O" high-performance NAND flash memory, optimized for on-device AI in smartphones, and its 10th generation V-NAND with over 400 layers. These advancements are tailored to meet the demands of AI environments requiring rapid data processing. SK Hynix, in collaboration with SanDisk, presented the standard specifications for its next-generation AI memory, High Bandwidth Flash (HBF). This technology stacks NAND flash chips in 8- and 16-layer configurations to increase capacity, addressing the surge in data processing needs for AI inference.

Industry analysts, such as George J. Lau from Yole Group, project that South Korea will retain its status as a memory powerhouse until 2031. This forecast is attributed to the South Korean government's plan to double its memory production capacity within five years and the substantial investments by Samsung and SK Hynix. Lau also noted that the rapid shift in the AI market from "training" to "inference" has shortened memory product development cycles from 18 to 12 months, necessitating swift adaptation from memory manufacturers.
