Decades of unrivaled leadership

Relentless innovation and the vision to see tomorrow - that’s what it takes to lead the world of flash memory.
Samsung has been No.1 in the flash memory market since 2003*, and has been pushing the boundaries of UFS since the market first
emerged in 2014. *Source: 2003-2021 OMDIA data: NAND suppliers' revenue market share.

23.2Gbps.
Flash forward

Blazing fast 5G, supercharged app performance, industry-beating read-write speeds – UFS 4.0 is here.
With a unique controller built and designed by Samsung, UFS 4.0
uses powerful 176-layer 7th Generation V-NAND to deliver 4,200MBps read speeds,
while MIPI M-PHY 5.0 offers up 23.2Gbps data transfers - doubling the speed of UFS 3.1.
Even write speeds get a 1.6x bump to 2,800MBps,
so your users can work, play, and create without limits.

46% more efficient.
Go further

Run smartphones longer, fly drones further, and take VR experiences deeper – without giving up a pixel on performance.
With 46% better power efficiency than the last generation, UFS 4.0 is designed to save on power even while it drives extraordinary performance.
At 6.0Mbps per 1mA of sequential read speed, users can take your best products further than ever.

Use of RPMB security solution technology
with 1.8 times enhanced performance

Your most intimate data is stored on your phone. UFS 4.0 keeps it safe from attacks with Advanced RPMB (Replay Protected Memory Block).
* UFS 4.0 is a full 1.8 times better at protecting data than the previous generation, so passwords, IDs, and your favorite memories all have a safe place to stay.
*Replay Protected Memory Block lets the system store data in a specific memory area
where it's authentication protected from replay attacks - so users can safely store important data like IDs or passwords.

1.0mm slim.
1TB capacity.
Work wonders

Made to fit the new era of slimmer, lighter devices, UFS 4.0 packs a whopping 1TB of memory into a slim 1.0mm form factor.
At just 13mm long and 11mm wide, it delivers a massive boost in performance without a bump in size - creating space
for tomorrow's top smartphone makers to explore all new possibilities.
