SAN JOSE, Calif.--(BUSINESS WIRE)--Feb 23, 2026--
KIOXIA America, Inc. today announced that it has begun shipping evaluation samples 1 of embedded flash memory compatible with the next-generation UFS standard, UFS 5.0, which is currently being standardized by JEDEC ®2.
This press release features multimedia. View the full release here: https://www.businesswire.com/news/home/20260223010301/en/
UFS 5.0 is a new standard for embedded flash storage designed to meet the performance requirements of next-generation mobile devices such as high-end smartphones equipped with on-device AI functions. It utilizes MIPI ® M-PHY ® version 6.0 for the physical layer and UniPro ® version 3.0 for the protocol. M-PHY version 6.0 introduces the new HS-GEAR6 mode, theoretically supporting an interface speed of up to 46.6 Gigabits per second (Gb/s) per lane; with 2 lanes, UFS 5.0 can achieve approximately 10.8 Gigabytes per second (GB/s) of effective read/write performance.
The evaluation samples incorporate a newly developed in-house controller for UFS 5.0 and KIOXIA BiCS FLASH™ generation 8 3D flash memory and support capacities of 512 GB and 1 TB. The package has been redesigned with a small 7.5 x 13 mm size, contributing to board space efficiency and design flexibility.
The samples are being provided to chipset vendors who are developing UFS 5.0-compatible host systems, enabling them to evaluate performance and conduct interoperability testing.
“Kioxia continues to drive innovation in embedded flash memory with the development of UFS 5.0 solutions designed for next-generation mobile applications,” said Maitry Dholakia, vice president, Memory Business Unit, KIOXIA America, Inc. “By delivering the high speeds and performance required for advanced on-device AI and providing early samples of high-capacity, high-speed solutions, we are helping customers accelerate the development and validation of future-ready smartphones.”
Kioxia will continue to introduce new flash memory technologies into its UFS products to meet the increasing demands for larger capacity and higher performance in the mobile market.

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.
Read and write speeds are the best values obtained in a specific test environment at Kioxia Corporation and Kioxia Corporation warrants neither read nor write speeds in individual devices. Read and write speed may vary depending on a device used and file size read or written.

TUCSON, Ariz. (AP) — The disappearance of “Today” show host Savannah Guthrie’s mother three weeks ago has inspired a small number of volunteers to launch their own searches in the dense desert near her home in hopes of cracking the case.
The Pima County Sheriff’s Department said while it appreciates the concern for Nancy Guthrie, it asked people inquiring about volunteering to give investigators space to do their jobs.
“We all want to find Nancy, but this work is best left to professionals,” the agency said in a statement over the weekend.
Nancy Guthrie, 84, was last seen at her home just outside Tucson on Jan. 31 and was reported missing the following day. Authorities believe she was kidnapped, abducted or otherwise taken against her will. Drops of her blood were found on the front porch, but authorities haven't publicly revealed much evidence.
Despite the sheriff's request for people not to search on their own, volunteers have continued to look. A small group reported finding a black backpack on Sunday, but it wasn't the same brand as one identified in video surveillance that the FBI released of a masked man at Guthrie's home the night she disappeared.
A sheriff's spokesperson told Tucson television station KOLD that the bag and its contents didn’t appear to be viable leads. The Associated Press reached out to the sheriff’s department for comment on Monday.
Two women from the group Madres Buscadoras de Sonora, or “Searching Mothers of Sonora,” who were carrying digging tools Sunday outside of Guthrie’s home, said they, too, would join the search. They posted fliers on Guthrie’s mailbox with her picture and their contact information.
Lupita Tello, who joined the group after her son disappeared in Mexico in 2020, said Monday she and two other volunteers will continue to post flyers on bus stops and utility poles near Nancy Guthrie's home. Members of the group plan to do the same in Nogales, Mexico.
She said the group was contacted by a friend of one of Nancy Guthrie's daughters who asked them for help because of their experience. The group has found the remains of more than 5,000 people in Mexico since it was started 10 years ago by mothers with missing children.
“We know the soil. We know when someone has dug deep or when there is a shallow grave,” Tello said. “We hope we can help because we understand the pain of having a missing relative.”
She said group members have received training by Mexican forensic experts on how to conduct their searches.
Tony Estrada, the former long-time sheriff in neighboring Santa Cruz County, said volunteer searchers have good intentions in wanting to help and can serve as a force multiplier, but it’s crucial that their efforts be coordinated with law enforcement.
“You can’t have people all over the place looking for something and not reporting to anybody or letting them know that they’re going to be in that area,” Estrada said. “They may be trampling into things that may come out to be helpful in the future.”
Nearly all search operations for U.S. law enforcement agencies are staffed with volunteers, said Chris Boyer, executive director of the National Association for Search and Rescue.
Untrained volunteers who show up to help in a search may mean well, but experts say they could end up contaminating a crime scene.
“It’s painful for law enforcement when that happens,” Boyer said.
Volunteers should undergo background checks, be trained in things like administering first aid and preserving crime scenes, and work under the direction of law enforcement authorities, said Boyer, whose group provides education, certification and advocacy for search and rescue efforts across the United States and other countries.
Several hundred people are working the Guthrie investigation, and more than 20,000 tips have been received, the sheriff's office has said. The FBI and other agencies are assisting.
The sheriff's office has watched around the clock lately at Guthrie's house. It also enacted a temporary one-way flow on the road so that emergency vehicles and trash collection trucks could get through. The constant presence of news crews, bloggers and curious onlookers has drawn mixed reaction from neighbors.
Some appreciated the attention the case has been getting. Others have placed traffic cones and signs on their properties to keep people off.
Meanwhile, the tribute to Nancy Guthrie outside her home keeps growing, with flowers, yellow ribbons, crosses, prayers and patron saints for older adults and in desperate situations.
Aran Aleamoni and his daughter Ariana picked out a bouquet of red, pink and white flowers and placed them at the edge of Guthrie’s yard, alongside a sign that read “Let Nancy Come Home” and a statuette of an angel.
“My heart goes out to the entire family,” said Aran Aleamoni, who has known the Guthrie family for a long time. “We are all pulling for you. We’re with you in your corner.”
