Kioxia Corporation is a major Japanese semiconductor manufacturer focused on flash memory and solid-state drive (SSD) technologies. As one of the world’s largest producers of NAND flash memory, Kioxia is widely credited as the inventor of the technology that underpins modern digital storage for smartphones, laptops, servers, AI systems, cameras, and data centers. 1

Origins at Toshiba

The lineage of Kioxia traces back to Toshiba Corporation, where engineers developed the world’s first NAND flash memory in 1987. This invention fundamentally changed digital storage by offering a medium that:

• Stores data without power (non-volatile)
• Operates faster than traditional hard drives
• Consumes less power
• Offers high durability
• Supports massive information density

Today, virtually every SSD, USB drive, smartphone storage chip, and memory card utilizes NAND flash technology derived from this original innovation.

Becoming Toshiba Memory

In 2017, Toshiba separated its memory business into a new entity named Toshiba Memory Corporation as part of a broader corporate restructuring effort. 2

The Birth of Kioxia

On October 1, 2019, Toshiba Memory officially rebranded as Kioxia Corporation. The name is a portmanteau of two words:

• Kioku (記憶) — Japanese for “memory”
• Axia — Greek for “value”

Together, Kioxia signifies “memory with value.” This rebranding reflected the company’s strategic ambition to establish itself as an independent global leader in memory technology.

Kioxia develops a comprehensive range of storage products catering to consumer, enterprise, and industrial markets.
