As mobile devices evolve to handle more complex tasks - like AI-driven applications and immersive multimedia - the need for high-performance, power-efficient storage has never been greater. Kioxia is meeting that need with its new UFS 4.1 embedded flash memory devices, now available for sampling.
Featuring our BiCS FLASH™ generation 8 3D flash memory and advanced CBA (CMOS Direct Bonded to Array) technology1, Kioxia’s new UFS 4.1 devices deliver faster speeds, improved power efficiency, and a slimmer package design compared to the previous generation2. These upgrades help device manufacturers meet the growing demands for higher performance without compromising size or battery life.
Our new lineup supports intelligent performance management, including host-initiated defragmentation and dynamic WriteBooster buffer allocation - features that enhance system responsiveness under real-world workloads. Offered in 256 GB, 512 GB, and 1 TB capacities, KIOXIA’s UFS 4.1 products are ready to power the next generation of mobile applications.
UFS has come a long way since Kioxia first introduced UFS samples back in 2013. Today’s mobile apps demand more from storage—more responsiveness, more efficiency, and more room to grow. KIOXIA’s UFS 4.1 devices deliver just that. Learn more about our latest UFS offerings in this press release.
1: 512 GB/1 TB models only.
2: The previous generation 1 TB device “THGJFMT3E86BATZ”.
In every mention of a KIOXIA product: Product density is identified based on the density of memory chips(s) within the product, not the amount of memory capacity available for data storage by the end user. In terms of product capacity, available user storage capacity (including examples of various media files) will vary based on file size, formatting, settings, software and operating system, pre-installed software applications, media content, and other constraints. Actual formatted capacity may vary. KIOXIA Corporation defines a gigabit (Gb) as 1,073,741,824 bits, a megabyte (MB) as 1,000,000 bytes, a gigabyte (GB) as 1,000,000,000 bytes and a terabyte (TB) as 1,000,000,000,000 bytes. However, a computer operating system, reports storage capacity using powers of 2 for the definition of 1 GB = 2^30 bytes = 1,073,741,824 bytes and 1 TB = 2^40 bytes = 1,099,511,627,776 bytes.
Universal Flash Storage (UFS) is a product category for a class of embedded memory products built to the JEDEC UFS standard specification. Due to its serial interface, UFS supports full duplexing, which enables both concurrent reading and writing between the host processor and UFS device.
