Kioxia Holdings Corporation (//), simply known as Kioxia and stylized as KIOXIA, is an American-Japanese multinational computer memory manufacturer headquartered in Tokyo, Japan. The company was spun off from the Toshiba conglomerate as Toshiba Memory Corporation (東芝メモリ株式会社, Tōshiba Memori Kabushikigaisha) in June 2018. It became a wholly owned subsidiary company of Toshiba Memory Holdings Corporation on March 1, 2019, and was renamed Kioxia in October 2019. In the early 1980s, while still part of Toshiba, the company was credited with inventing flash memory. In the second quarter of 2021, the company was estimated to have 18.3% of the global revenue share for NAND flash solid-state drives. The company is the parent company of Kioxia Corporation.
Kioxia is a combination of the Japanese word kioku meaning memory and the Greek word axia meaning value.

On June 1, 2018, due to heavy losses experienced by the bankruptcy of the Westinghouse[which?] subsidiary of former parent company Toshiba over nuclear power plant construction at Vogtle Electric Generating Plant in 2016, Toshiba Memory Corporation was spun off from the Toshiba Corporation. Toshiba maintained a 40.2% equity in the new company. The new company consisted of all of Toshiba memory businesses.
