History
See also: Toshiba § History

In January 2014, the Toshiba Corporation completed its acquisition of OCZ Storage Solutions renaming it to OCZ and making it a brand to Toshiba.[7]

On June 1, 2018, Toshiba Memory Corporation was spun off from the Toshiba Corporation. Toshiba maintained a 40.2% equity in the new company.[2] 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.[8][9]

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.[2] This renaming also included companies associated with Toshiba's solid-state drive brand OCZ.[10]

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.[11][12]
