Universal Flash Storage (UFS)

Your computing and mobile devices require the ever-increasing high performance and energy efficiency that the Universal Flash Storage (UFS) interface was designed for. Our UFS 2.1 products — the next-generation successor to the e.MMC 5.1 interface options — are set to enable your ultra-fast user experiences.

The Ultra-Fast UFS Advantage

UFS is a high-performance storage interface ideal for computing and mobile systems that require low power consumption. We’re using the UFS 2.1 standard in our UFS multichip packages (uMCPs) and discrete UFS devices  to enable your ultra-fast mobile user experiences.

Build in our UFS products and get:

  • Significantly faster random read speeds than with the e.MMC 5.1 interface.
  • Industry-leading sequential read performance (600 MB/s of max I/F bandwidth) with the High-Speed Gear 3 specification. 
  • More efficient multitasking and data ordering thanks to UFS 2.1’s Command Queue technology,  which enables read and write commands simultaneously, different from e.MMC interfaces.

Benefits for Mobile

UFS is the ideal interface for next-gen mobile devices, and here’s why:

  • Performance: Enables much quicker load times for applications and files as well as faster device boot-up compared to e.MMC 5.1.
  • Multi-Tasking Responsiveness: Provides a seamless experience when switching between multiple applications due to lower UFS latencies. 
  • Camera Performance: Enables a significant increase in performance over e.MMC 5.1 when shooting bursts of photos or multiple photo stitches like panoramas due to higher memory interface bandwidth.
  • Richer Content: Enables seamless HD streaming and more graphically rich content (like in gaming) thanks to the faster read/write performance with UFS.


In late August, we announced our first ever mobile 3D NAND memory products, enabling our smartphone customers to pack in a lot more storage capacity into a smaller footprint. While bringing this new 3D architecture to mobile is significant, perhaps even more exciting was our...
