== Name ==
Kioxia is a combination of the Japanese word ''kioku'' meaning ''memory'' and the Greek word ''axia'' meaning ''value''.<ref name="zd1">{{Cite web |date=2019-07-19 |title=Former Toshiba memory business to rebrand as Kioxia |url=https://www.zdnet.com/article/former-toshiba-memory-business-to-rebrand-as-kioxia/ |access-date=2020-03-09 |publisher=ZDNet}}</ref>

== History ==
In 1980, Fujio Masuoka, an engineer at Kioxia predecessor Toshiba, invented flash memory,<ref>{{patent|US|4531203|Fujio Masuoka}}</ref><ref>{{US patent|4531203|Semiconductor memory device and method for manufacturing the same}}</ref> and in 1984, Masuoka and his colleagues presented their invention of [[Flash memory#NOR memories|NOR]] flash.<ref>{{Cite book |last1=Masuoka |first1=F. |last2=Asano |first2=M. |last3=Iwahashi |first3=H. |last4=Komuro |first4=T. |last5=Tanaka |first5=S. |title=1984 International Electron Devices Meeting |chapter=A new flash E<sup>2</sup>PROM cell using triple polysilicon technology |date=December 1984 |pages=464–467 |doi=10.1109/IEDM.1984.190752|s2cid=25967023 }}</ref>

In January 2014, the Toshiba Corporation completed its acquisition of OCZ Storage Solutions, renaming it OCZ and making it a brand of Toshiba.<ref>{{Cite magazine |last=Martyn Williams |title=It's official: Toshiba owns OCZ's SSD business |url=http://www.pcworld.com/article/2090061/toshiba-completes-acquisition-of-ocz-storage.html |magazine=PCWorld |access-date=20 March 2014}}</ref>

On June 1, 2018, due to heavy losses experienced by the bankruptcy of the Westinghouse{{which|date=November 2021}} 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.<ref name=wsj1/><ref name=":0">{{Cite web |title=Company information &#124; KIOXIA |url=https://www.kioxia-holdings.com/en-jp/about/company.html |website=www.kioxia-holdings.com}}</ref> 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.
