SK Hynix’s Latest Innovation
SK Hynix Inc. has made headlines once again by starting mass production of the world’s first 1TB triple-level cell-based 321-high 4D NAND flash. This breakthrough follows their achievement of providing the highest 238-layer NAND technology last year. With this recent innovation, SK Hynix has now become the first in the industry to surpass 300 layers in NAND production, showcasing their commitment to technological advancement.
Technological Advancements in NAND Flash
The expansion to 321-high layers signifies a remarkable leap in NAND flash technology. This feat was accomplished through a significant technological breakthrough in stacking processes. The innovative approach, termed the “3 plugs” process technology, allows for an electrical connection of three plugs after an optimized follow-up process, significantly enhancing production efficiency.
Future Plans and Market Impact
Looking ahead, SK Hynix plans to offer these advanced 321-high products to its customers starting in the first half of next year. The development of low-stress materials and automatic alignment correction for the plugs indicates that the company is not only focusing on the performance but also on the reliability of their products. This advancement is expected to have a substantial impact on the market, setting a new standard for NAND flash technology and pushing competitors to innovate further.
