Kioxia, the Japanese memory giant formerly known as Toshiba Memory, has started shipping evaluation samples of its next-generation flash memory chips to AI data center operators.
What Kioxia is actually shipping
The company has been rolling out UFS 5.0 embedded flash memory samples built on its 8th-generation BiCS FLASH technology. The 512 GB evaluation samples shipped in February 2026, with 1 TB versions following in March 2026.
BiCS FLASH is Kioxia’s brand name for its 3D NAND technology, which stacks memory cells vertically rather than spreading them across a flat surface.
The GP Series, a line of super high IOPS SSDs announced in March 2026, is designed to let GPUs access flash storage directly, cutting out the middleman processes that typically slow things down.
