Kioxia Begins Sample Shipments of 10th-Gen BiCS FLASH for AI Storage Demand
Kioxia has started shipping samples of its 10th-generation BiCS FLASH™ 3D flash memory, marking a major step forward for AI-era storage. The new 1-terabit (1Tb) Triple-Level-Cell (TLC) chips hit a NAND interface speed of 4.8 gigabits per second — a 33% jump over the company's 8th-generation devices, according to National Post.
The chips are aimed squarely at enterprise and data center solid-state drives (SSDs). As AI workloads demand faster, denser, and more energy-efficient storage, Kioxia is betting this technology puts it ahead of the curve.
Two Key Technologies Power the Speed Leap
The 10th-generation BiCS FLASH™ relies on two core innovations. The first is CMOS Directly Bonded to Array (CBA) technology. This bonds the chip's control circuits directly onto the memory array, making the chip smaller and faster. The second is On-Pitch Select Gate Drain (OP) technology, which improves how the chip reads and writes data, according to Montreal Gazette.
Together, these two advances let Kioxia pack more storage into a smaller space while using less power. That combination is critical for data centers, which are under pressure to cut electricity costs even as AI demand surges.
AI Storage Demand Is Driving Kioxia's Push
AI systems require enormous amounts of fast, reliable storage. Large language models and AI training jobs read and write massive datasets constantly. Slow or power-hungry storage becomes a bottleneck. Kioxia is targeting that gap directly with this new chip, The Sudbury Star reported.
The 1Tb capacity per chip means storage makers can build denser SSDs with fewer chips. Fewer chips means less power, less heat, and lower cost per gigabyte — all things data center operators care deeply about.
New Fab in Japan Will Manufacture the Chips
Kioxia will produce the 10th-generation devices at its Kitakami Plant Fab2 facility in Iwate Prefecture, Japan. The plant uses state-of-the-art equipment and represents a significant manufacturing investment, according to Hanna Herald.
Building a dedicated fab for next-generation memory keeps production close to Kioxia's engineering teams and reduces supply chain risk. Japan has been actively supporting domestic semiconductor manufacturing, making this investment well-timed.
What a 33% Speed Gain Means in Practice
Going from the 8th-generation's roughly 3.6 Gb/s to 4.8 Gb/s may sound technical, but the real-world impact is clear. SSDs built with these chips can move data to and from a server's processor much faster. For AI inference — where a model answers a question in real time — every millisecond matters, The Whig reported.
Kioxia's sample shipments are the first step before mass production. Enterprise customers will test the chips in their own systems before placing large orders. If testing goes well, these devices could appear in commercial data center SSDs within the next year or two.
