ZUFS, or Zoned UFS[1], is an extended specification of UFS[2] that applies Zoned Storage technology, which stores data in different zones based on its usage and characteristics.
[1] Zoned UFS (ZUFS): First introduced by the Joint Electron Device Engineering Council (JEDEC) in 2023 as an extended specification of UFS. Development of ZUFS 4.1, based on the JEDEC UFS 4.1 standard, was completed in 2025. |
[2] Universal Flash Storage (UFS): A high-speed flash memory storage specification for mobile devices such as smartphones and tablets. Since the launch of UFS 1.0 in 2011, the specification has evolved through versions 2.0 (2013), 2.1 (2016), 3.0 (2018), 3.1 (2020), 4.0 (2022), and 4.1 (2025), with each version significantly improving data transfer speed and power efficiency. |
When installed in a smartphone, ZUFS 4.1 enhances the operation speed of the operating system (OS) and improves data management efficiency. As a result, it mitigates read performance degradation over extended use by more than four times compared to conventional UFS, enabling a
These performance characteristics position ZUFS 4.1 as an optimal solution for today's mobile environment, where on-device AI and large-scale data processing are essential.
In addition, SK hynix has significantly enhanced the error-handling capabilities of ZUFS 4.1 compared to version 4.0 developed in May 2024. By detecting errors with greater precision and clearly communicating the necessary corrective actions to the central processing unit, the latest solution is expected to significantly improve system reliability and recovery performance.
"ZUFS 4.1, which we have successfully begun to supply, is the first solution developed and mass-produced through collaboration aimed at optimizing Android OS and storage devices. Looking ahead, its applications are expected to expand," said Justin Kim, President & Head of AI Infra at SK hynix.
"We will continue to supply NAND solutions that meet customer needs in a timely manner, while strengthening partnerships with global companies to strengthen our competitive edge in the AI memory sector."
