JEDEC® Updates Universal Flash Storage (UFS) and Supporting Memory Interface Standard
JEDEC Solid State Technology Association, the global leader in the development of standards for the microelectronics industry, today announced the publication of JESD220F: Universal Flash Storage 4.0. In addition, an update to the complementary JESD223E UFSHCI 4.0 standard, and a new companion standard for UFS version 3.1 and above, JESD231 File Based Optimization, have also been published. Developed for mobile applications and computing systems requiring high performance with low power consumption, UFS 4.0 introduces significant bandwidth and data protection improvements over the earlier version of the standard. All three standards are available for download from the JEDEC website.
UFS is a high performance interface designed for use in computing and mobile systems such as smart phones and tablets where power consumption needs to be minimized. Its high speed serial interface and optimized protocol enable significant improvements in throughput and mobile system performance. UFS 4.0 & UFSHCI 4.0 together define the following major improvements over the prior version of the standard:
In addition, UFS 4.0 offers several enhancements designed to increase overall device capability, power efficiency and ease of integration wit tomorrow's leading-edge solutions:
Finally, as an optional extension to UFS version 3.1 and above, the new JESD231 File Based Optimization standard allows a host to accelerate read traffic based on the File System information provided by the host.
"JEDEC members are dedicated to developing the standards needed to support the mobile devices of the future," said Mian Quddus, Chairman of the JEDEC Board of Directors and the JC-64 Committee for Embedded Memory Storage and Removable Memory Cards. He added, "The ongoing efforts to continually improve UFS and its companion standards will in turn enable significant advancements in device performance and an enhanced user experience."
"By collaborating with JEDEC, we're advancing memory standards like UFS4 for a range of emerging applications," said Thierry Berdah Kraz, product management director at Cadence. "Cadence supports the early adoption of the standard and helps customers accelerate verification at the IP and SoC levels during the development of complex memory designs with optimal performance and power-efficiency."
"Kioxia is very honored to be part of the team that is instrumental in standardizing this latest UFS version. We know that the significant increase in performance and new features added to UFS4.0 will definitely translate to another round of improved user experiences, as UFS adaptation further expands to even more applications," said Atsushi Inoue, Senior Director, Memory Division, KIOXIA Corporation.
"The UFS 4.0 standard will be a game changer for NAND flash storage in smartphones," said Raj Talluri, senior vice president and general manager of Micron's Mobile Business Unit. "Delivering blazingly fast read and write speeds that significantly reduce app and game load times, as well as improved power efficiency, UFS 4.0 has the potential to usher in significant improvements that will enable future user experiences and emerging mobile applications."
"With rapid advancements in the design of smartphones and other consumer devices, mobile storage solutions have also had to evolve quickly in accommodating the greater speed and bandwidth requirements," said Kyungryun Kim, vice president of the NAND Memory Planning/Enabling Group at Samsung Electronics. "Featuring twice the performance of UFS 3.1, the new UFS 4.0 JEDEC standard will be essential for powering the latest innovations in mobile technology."
"High-performance interfaces such as UFS 4.0 continue to be critical to address the growing requirements for faster bandwidth, lower power consumption and embedded security in mobile devices," said John Koeter, senior vice president of Marketing and Strategy, Synopsys Solutions Group. "The Synopsys UFS 4.0 IP has been adopted by multiple leading mobile customers, and when combined with Synopsys UniPro Controller, M-PHY IP and verification IP, provides a complete solution that accelerates the integration of the required functionality, reduces design risk, and eases development of power-efficient and secure SoCs for mobile applications."
JEDEC is the global leader in the development of standards for the microelectronics industry. Thousands of volunteers representing over 340 member companies work together in more than 100 JEDEC committees and task groups to meet the needs of every segment of the industry, manufacturers and consumers alike. The publications and standards generated by JEDEC committees are accepted throughout the world. All JEDEC standards are available for download from the JEDEC website.
