KIOXIA's 9th Generation BiCS FLASH™ unveiled: A leap in memory technology

KIOXIA Europe introduces its 512Gb TLC memory with groundbreaking 9th generation BiCS FLASH™ technology, aiming for mass production by 2025.

KIOXIA Europe has commenced sample shipments of its 512Gb Triple-Level Cell (TLC) memory devices featuring the latest 9th generation BiCS FLASH™ 3D flash memory technology. Mass production is planned for fiscal year 2025. They were designed to support applications that demand high performance and exceptional power efficiency in low to mid-level storage capacities. These devices will be integral to KIOXIA’s enterprise SSDs, notably those enhancing GPU efficiency in AI systems.

In its quest to meet the needs of cutting-edge applications, KIOXIA adopts a dual-axis strategy aimed at both competitive product delivery and investment efficiency:

  • 9th generation BiCS FLASH™ products: Achieving high performance with reduced production costs by leveraging CBA (CMOS directly Bonded to Array) technology. This approach integrates existing memory cell technologies with the latest CMOS technology.
  • 10th generation BiCS FLASH™ products: Featuring expanded memory layers to cater to future demands for larger capacity, high-performance solutions.

Developed using a 120-layer stacking process and advanced CMOS technology, the 9th generation BiCS FLASH™ 512Gb TLC shows remarkable improvements over existing BiCS FLASH products with an equivalent capacity:

  • Write performance: 61% improvement
  • Read performance: 12% enhancement
  • Power efficiency: Improved by 36% during write and 27% during read operations
  • Data transfer speed: Enabled by the Toggle DDR6.0 interface, achieving 3.6Gb/s NAND interface performance
  • Bit density: Increased by 8% through advancements in planar scaling

Demonstrations have confirmed the 512Gb TLC can operate at NAND interface speeds up to 4.8Gb/s. The product line-up will align with market demands ensuring efficient solutions for various sectors, from Internet of Things and automotive to cloud storage and AI-heavy tasks.

KIOXIA remains dedicated to enhancing global partnerships and relentless innovation to deliver solutions finely tuned to customer needs worldwide.
