1. Historical Background  <\/strong><\/strong><\/p>

– Toshiba is Kioxia\u2019s predecessor: Kioxia originated from \u201cToshiba Memory Corporation\u201d, which was formerly Toshiba Group\u2019s semiconductor memory business unit, renowned for its NAND flash memory technology (Toshiba was one of the inventors of flash memory).  <\/p>

– Toshiba\u2019s financial crisis led to divestment: In 2017, Toshiba faced financial difficulties and decided to sell its memory business to alleviate financial pressure. In 2018, the business was acquired by a consortium led by Bain Capital, though Toshiba retained a partial stake (currently about 40%).  <\/p>

2. Independence and Rebranding  <\/strong><\/strong><\/p>

– Rebranded as Kioxia in 2019: In October 2019, Toshiba Memory Corporation officially changed its name to \u201cKioxia Holdings Corporation\u201d (Chinese name: \u94e0\u4fa0\u63a7\u80a1). The name combines the Japanese word for “memory” (\u8a18\u61b6, *kioku*) and the Greek word for “value” (*axia*), symbolizing the “value of memory.” Toshiba remains a shareholder, but Kioxia operates as an independent company.  <\/p>

3. Current Relationship  <\/strong><\/strong><\/p>

– Toshiba is a shareholder of Kioxia: Toshiba holds approximately 40% of Kioxia\u2019s shares, but Kioxia operates independently and is no longer a subsidiary of Toshiba Group.  <\/p>

– Business collaboration: The two companies continue to cooperate in areas like R&D (e.g., flash memory production) and patent licensing, though Kioxia\u2019s product lines (e.g., SSDs, UFS) are not directly tied to Toshiba\u2019s other businesses.  <\/p>

– Competitive dynamics: Toshiba Group retains some semiconductor operations (e.g., system LSI), which do not directly compete with Kioxia. However, Toshiba competes with other memory manufacturers (e.g., Samsung).  <\/p>

 4. Key Milestones  <\/strong><\/strong><\/p>

2017: Toshiba sold its memory business to the Bain consortium.  <\/p>

2018: Toshiba Memory Corporation was established (with Toshiba retaining partial ownership).  <\/p>

2019: Official rebranding to Kioxia and launch of the new brand.  <\/p>

Summary  <\/strong><\/strong><\/p>

Kioxia is essentially the “successor” to Toshiba\u2019s memory business but has become an independent entity through restructuring and rebranding. Toshiba remains a shareholder with financial interests but does not participate in daily operations. Their relationship resembles a “parent and child parting ways” while maintaining ties in technology and capital.  <\/p>","protected":false},"excerpt":{"rendered":"

Kioxia, spun off from Toshiba’s memory division in 2019, operates independently while Toshiba retains a 40% stake. The rebranded company (merging Japanese “kioku” and Greek “axia”) focuses on flash memory innovation. Though they collaborate on R&D, Kioxia runs autonomously in the competitive semiconductor market.<\/p>\n","protected":false},"author":1,"featured_media":707,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[8],"tags":[],"class_list":["post-705","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-industry-news"],"_links":{"self":[{"href":"http:\/\/www.timeswin.com.hk\/index.php?rest_route=\/wp\/v2\/posts\/705","targetHints":{"allow":["GET"]}}],"collection":[{"href":"http:\/\/www.timeswin.com.hk\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"http:\/\/www.timeswin.com.hk\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"http:\/\/www.timeswin.com.hk\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"http:\/\/www.timeswin.com.hk\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=705"}],"version-history":[{"count":1,"href":"http:\/\/www.timeswin.com.hk\/index.php?rest_route=\/wp\/v2\/posts\/705\/revisions"}],"predecessor-version":[{"id":708,"href":"http:\/\/www.timeswin.com.hk\/index.php?rest_route=\/wp\/v2\/posts\/705\/revisions\/708"}],"wp:featuredmedia":[{"embeddable":true,"href":"http:\/\/www.timeswin.com.hk\/index.php?rest_route=\/wp\/v2\/media\/707"}],"wp:attachment":[{"href":"http:\/\/www.timeswin.com.hk\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=705"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/www.timeswin.com.hk\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=705"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/www.timeswin.com.hk\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=705"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
