Kioxia and Sandisk unveil new 332-layer 3D NAND for data centers
Key points
- New 332-layer BiCS10 NAND starts sampling by Kioxia and Sandisk.
- Designed specifically for data center applications, not consumer devices.
- Offers 59% higher bit density and reduced read latency and energy consumption.
Introduction to BiCS10 3D NAND
Kioxia and Sandisk have launched the sampling phase of their latest 3D NAND memory, the 10th Generation BiCS, featuring an innovative architecture of 332 active layers. This new technology is claimed to rival and surpass Samsung’s V10-class 3D NAND in storage density, focusing primarily on data center applications rather than consumer devices.
Key Features and Performance Improvement
The BiCS10 NAND is engineered for high-density performance, achieving over 29 Gb/mm² in density and a data transfer rate of 4,800 MT/s. These capabilities are crucial for data center SSDs utilizing PCIe 5.0 and 6.0 interfaces, setting the stage for enhanced data handling efficiency.
Efficiency and Latency Gains
Kioxia reports that the new design yields significant operational advantages, including a 10% reduction in read latency and a 25% decrease in read energy consumption (from 100 mJ/GB to 75 mJ/GB). These improvements are attributed to a redesigned read scheme that optimizes how unselected word lines are managed during operations.
Target Market and Future Availability
Unlike its predecessors, the BiCS10 NAND is not marketed towards consumer devices, with Kioxia specifically targeting enterprise-grade solutions. Whether version 10 will transition to high-performance consumer SSDs will depend largely on market demand.
