Kioxia Holdings Corporation, simply known as Kioxia and stylized as KIOXIA, is a 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 Kabushiki-gaisha) in 2018. It became a wholly owned subsidiary company of Toshiba Memory Holdings Corporation on March 1, 2019 and was renamed to Kioxia in October 2019. In the third quarter of 2018, the company was estimated to have 19% of the global revenue share for NAND flash solid-state drives. The company is the parent company of Kioxia Corporation.
On June 1, 2018, 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. Toshiba Memory Corporation became a subsidiary of the newly formed Toshiba Memory Holdings Corporation on March 1, 2019.
In June 2019, Kioxia experienced a power cut at one of its factories in Yokkaichi, Japan, resulting in the loss of at least 6 exabytes of flash memory, with some sources estimating the loss as high as 15 exabytes. Western Digital used (and still uses) Kioxia's facilities for making its own flash memory chips.
On July 18, 2019, Toshiba Memory Holdings Corporation announced it would change its name to Kioxia on October 1, 2019, including all Toshiba memory companies. On October 1, 2019, Toshiba Memory Holdings Corporation was renamed to Kioxia Holdings Corporation and Toshiba Memory Corporation was renamed to Koixia Corporation. This renaming also included companies associated with Toshiba's solid-state drive brand OCZ.
On August 30, 2019, Toshiba Memory Holdings Corporation, not yet renamed to Kioxia, announced that it signed a definitive agreement to acquire Taiwanese electronics manufacturer Lite-On's SSD business for US$165 million. The transaction is expected to close by the first half of 2020.
