JEDEC Sets Stage for Next Leap in Flash Storage, UFS 5.0 is Coming

JEDEC Solid State Technology Association announced it is nearing completion of the next version of its highly anticipated Universal Flash Storage (UFS) standard: UFS 5.0.Designed for mobile applications and computing systems that demand high performance with low power consumption, UFS 5.0 plans to deliver faster data access and improved performance compared to its predecessor, while maintaining compatibility with UFS 4.x hardware.

UFS offers high-performance, embedded storage with low power consumption, making it ideal for use in applications where power efficiency is essential. This includes computing and mobile systems like smartphones and wearables, as well as an expanding role in automotive applications, edge computing and gaming consoles. Its high-speed serial interface and optimized protocol enable significant throughput for power-efficient system performance.

UFS 5.0 will include the following and other features:

Increased sequential performance up to 10.8GB/s to meet AI demands ^(*)
Integrated link equalization for more reliable signal integrity ^(*)
Distinct power supply rail to provide noise isolation between PHY and memory subsystem, easing system integration ^(*)
Inline Hashing for greater security

Stay tuned for more: JEDEC is continuing to evaluate features for further enhancements to the standard when published. JEDEC encourages companies to join and help shape the future of JEDEC standards. JEDEC membership provides access to pre-publication proposals and early insights into active projects such as UFS 5.0 and more.

“JEDEC members are continually shaping the standards that will drive the next generation of mobile devices and advanced applications, and the committee’s dedication to ongoing improvements to the UFS series is paving the way for future innovation,” said Mian Quddus, chairman, board of directors and JC-64 committee for embedded memory storage and removable memory cards, JEDEC.

Collaboration with MIPI Alliance
To achieve the highest performance and most power efficient data transport, JEDEC UFS leverages industry-leading specifications from the MIPI Alliance to form its Interconnect Layer. This collaboration continues with UFS 5.0, which leverages the upcoming MIPI M-PHY version 6.0 specification and the UniPro version 3.0 specification. M-PHY 6.0 introduces a new High-Speed Gear 6 (HS-G6), which supports data rates double those of the previous maximum data rate of HS-G5, enabling UFS interface bandwidth of 46.6Gb/s per lane and supporting up to ~10.8GB/s effective read/write operation for UFS 5.0 over 2 M-PHY lanes.
