JEDEC announces UFS 5.0 — faster, more efficient embedded storage

JEDEC is finalizing UFS 5.0, the next-generation Universal Flash Storage standard designed for devices that need high speed with low power use. UFS 5.0 aims to boost data access and overall performance while staying compatible with existing UFS 4.x hardware.

Why UFS matters for mobile devices

• High performance with low power — UFS is built for embedded storage in phones, wearables, laptops, and other systems where battery life and speed both matter.
• Broader applications — Beyond mobile, UFS is increasingly used in automotive systems, edge computing, and gaming consoles because of its efficient, high-throughput interface.
• Optimized interface and protocol — The UFS serial link and protocol maximize throughput while keeping power consumption low.

Key highlights of UFS 5.0

• Much faster sequential speeds — Up to about 10.8 GB/s to better handle AI workloads and large data transfers.
• Improved signal reliability — Integrated link equalization for more dependable high-speed communication.
• Cleaner power design — A separate power rail for the PHY and memory subsystem reduces noise and simplifies system integration.
• Built-in security — Inline hashing to strengthen data integrity and device security.

Industry collaboration

UFS 5.0 continues JEDEC's partnership with the MIPI Alliance. It leverages the new MIPI M-PHY 6.0 and UniPro 3.0 specifications. M-PHY 6.0 adds a new high-speed gear that doubles prior lane rates, enabling roughly 46.6 Gb/s per lane and delivering the ~10.8 GB/s effective throughput over two lanes for UFS 5.0.

What's next

JEDEC is still evaluating additional features before the final publication. Companies are invited to join JEDEC to participate in developing standards, get early access to proposals, and influence the next wave of UFS improvements.

Leadership view

JEDEC leadership emphasizes that member-driven work on UFS is helping shape storage standards for future mobile devices and advanced applications, with ongoing committee efforts focused on continuous improvement and innovation.
