Kioxia’s BiCS FLASH™ 3D flash memory and LC9 Series SSD exemplify innovation at its finest. By combining CBA (CMOS directly Bonded to Array) technology with a revolutionary 32-die stacked architecture, Kioxia has created an SSD that meets the demanding requirements of modern data centers. Delivering the highest capacity(2) PCIe® 5.0 enterprise SSD is no small feat—it underscores Kioxia’s leadership in the memory and storage industry.”
At the heart of the KIOXIA LC9 Series is a 32-die stack of 2 terabit (Tb)(3) BiCS FLASH™ QLC 3D flash memory, enabled by Kioxia’s proprietary CBA technology. This advanced architecture allows for an incredible 8 TB(3) of storage in a compact 154 BGA package—a first-of-its-kind achievement(2). Such density is made possible through Kioxia’s advancements in high-precision wafer processing, material design, and wire bonding technologies, setting new standards for capacity and efficiency in enterprise storage.
Tailored for the Next Wave of AI-Centric Workloads
As enterprises increasingly adopt AI-driven solutions, the need for high-capacity, high-performance storage has never been greater. The KIOXIA LC9 Series is specifically engineered to support the next wave of AI-centric workloads, offering the speed, scale, and density required to handle complex computational tasks. Its PCIe® 5.0 interface ensures lightning-fast data transfer rates, enabling seamless operation in data-intensive environments.
Moreover, the SSD’s innovative design addresses key challenges faced by modern data centers, including power consumption and physical space constraints. By delivering unparalleled storage density in a compact form factor, the KIOXIA LC9 Series helps organizations optimize their infrastructure while reducing operational costs.
A Testament to Kioxia’s Leadership
The recognition of Kioxia’s LC9 Series SSD at FMS 2025 highlights the company’s commitment to pushing the boundaries of what’s possible in memory and storage technology. As one of the pioneers of 3D flash memory, Kioxia continues to lead the industry with innovations like BiCS FLASH™ and CBA technology. These advancements not only enhance the capabilities of SSDs but also pave the way for future breakthroughs in storage solutions.
Technical Insights and Industry Impact
Understanding the technical nuances of the KIOXIA LC9 Series underscores its significance. Kioxia defines storage capacity using decimal notation (e.g., 1 TB = 1,000,000,000,000 bytes), while operating systems typically use binary notation (e.g., 1 TB = 1,099,511,627,776 bytes). This discrepancy means users may see slightly lower reported capacities, depending on the system. However, the actual formatted capacity remains exceptional, ensuring ample space for large-scale applications and datasets.
The flash memory’s capacity is calculated using binary definitions, with 1 terabit (1 Tb) equaling 1,099,511,627,776 bits and 1 terabyte (1 TB) equaling 1,099,511,627,776 bytes. These precise measurements reflect Kioxia’s dedication to accuracy and transparency in product specifications.
