Kioxia Sampling UFS Ver. 4.1 Embedded Flash Memory Devices

TOKYO--(BUSINESS WIRE)--Jul 8, 2025--

Kioxia Corporation, a world leader in memory solutions, today announced that it has begun sampling new Universal Flash Storage (2) (UFS) Ver. 4.1 embedded memory devices, reinforcing its leadership in high-performance storage. Engineered to meet the demands of next-generation mobile applications, including advanced smartphones with on-device AI, the new devices offer improved performance with greater power efficiency (3), in a small BGA package.

This press release features multimedia. View the full release here: https://www.businesswire.com/news/home/20250707306499/en/

UFS Ver. 4.1 devices from Kioxia integrate the company’s innovative BiCS FLASH™ 3D flash memory and a controller in a JEDEC-standard package. These new UFS devices are built with Kioxia’s 8th generation BiCS FLASH™ 3D flash memory (1). This generation introduces CBA (CMOS directly Bonded to Array) technology—an architectural innovation that marks a step-change in flash memory design. By directly bonding the CMOS circuitry to the memory array, CBA technology enables major gains in power efficiency, performance and density.

With a blend of speed and low power use, Kioxia’s UFS Ver. 4.1 devices are built to enhance user experiences—enabling faster downloads and smoother app performance.

Notes:
(1) 512 GB / 1 TB models only.
(2) 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.
(3) Compared to the previous generation 512 GB device “THGJFMT2E46BATV” and 1 TB device “THGJFMT3E86BATZ” respectively (512 GB / 1 TB models only).
(4) The previous generation 1 TB device “THGJFMT3E86BATZ”.

*In every mention of a Kioxia product: Product density is identified based on the density of memory chip(s) within the Product, not the amount of memory capacity available for data storage by the end user. Consumer-usable capacity will be less due to overhead data areas, formatting, bad blocks, and other constraints, and may also vary based on the host device and application. For details, please refer to applicable product specifications. The definition of 1 KB = 2^10 bytes = 1,024 bytes. The definition of 1 Gb = 2^30 bits = 1,073,741,824 bits. The definition of 1 GB = 2^30 bytes = 1,073,741,824 bytes. 1 Tb = 2^40 bits = 1,099,511,627,776 bits. 1 TB = 2^40 bytes = 1,099,511,627,776 bytes.

Kioxia: UFS Ver. 4.1 Embedded Flash Memory Devices for Next-generation Mobile Applications

LIMA, Peru (AP) — Peru’s Congress on Wednesday elected legislator José María Balcázar as the country's eighth president in a decade, replacing another interim leader who was ousted the previous day over corruption allegations just four months into his term.

Balcázar, an 83-year-old former judge representing the leftist Perú Libre party, defeated three other candidates with a majority of the 130-member legislature.

The revolving-door presidency in Peru reflects a political crisis fueled by a lack of legislative majorities for leaders. Lawmakers have frequently used a broad interpretation of a constitutional article regarding “permanent moral incapacity” to remove sitting presidents.

On Tuesday, Congress voted to remove conservative interim president José Jerí after four months in office. The current Congress, which began its term in 2021, has now impeached three heads of state: Pedro Castillo, Dina Boluarte and Jerí.

In October 2025, Jerí was serving as president of Congress and was next in the line of succession to replace Boluarte, who had no vice presidents.

His own removal followed revelations regarding his undisclosed meetings with Chinese business owners, including a state contractor. Jerí asserted he was merely coordinating a Peruvian-Chinese festival.

The Public Prosecutor’s Office has launched two preliminary investigations into Jerí over allegations of illegal sponsorship of private interests and influence-peddling to the detriment of the state.

The new president will govern for five months before handing over power to the winner of general elections on April 12, when Peruvians will choose a new president and legislature. If no presidential candidate receives more than 50% of the vote, the two front-runners will advance to a runoff election in June.

Balcázar successor will confront a surge in murders and extortion that continues to devastate small business owners and the working class.

Various political groups are demanding firm guarantees for a transparent election.
