Last Updated on July 25, 2023 by Team Yantra

Micron today announced that it is now delivering qualification samples of its Universal Flash Storage (UFS) 4.0 mobile solution, built on its advanced 232-layer 3D NAND. Offered in high capacities of up to 1 terabyte (TB), the UFS 4.0 storage solution is being shipped to select global smartphone manufacturers and chipset vendors.

For those who need a bit of background, the UFS stands for Universal Flash storage. It is a storage technology, which is used in current smartphones and devices to store data. Just like SSDs in laptops, we have UFS in smartphones. The higher the UFS version, the faster and better it is. Like UFS 4.0 is the latest version, which is much faster than the previous version, UFS v3.1. We have already written a detailed articled on UFS with its origin, technology and more.

Micron’s newest mobile flash storage outpaces the competition on several critical NAND benchmarks, delivering the industry’s fastest performance for flagship smartphones with fast bootup, app launches, and video downloads.

Together, these technologies position Micron at the forefront of delivering the performance and low-power innovations our customers need to enable an exceptional end-user experience for flagship smartphones
