- Brand and Core Technology Overview
As a world-leading provider of flash memory and solid-state drive (SSD) solutions, KIOXIA traces its origins to Toshiba Memory Corporation. It officially rebranded and operated independently in 2019, with headquarters in Tokyo, Japan. The name "KIOXIA" fuses "kioku" (Japanese for "memory") and "axia" (Greek for "value"), embodying its mission to create social value via storage technology.KIOXIA’s technological foundation lies in inventing the world’s first non-volatile NAND flash in 1987—a breakthrough that underpins modern information societies. Today, its core BiCS FLASH 3D NAND flash has evolved to the 10th generation, delivering capacity and performance leaps through vertical stacking. The upcoming mass-produced 332-layer product adopts CMOS Direct Bonding (CBA) technology, boosting storage density by 59%, reaching 4.8Gb/s interface speed, and cutting input/output power consumption by 10%/34% respectively, setting an industry energy efficiency benchmark. Leveraging Yokkaichi (one of the world’s largest flash facilities) and Kitakami plants, KIOXIA meets global demand via AI-driven advanced manufacturing.
