Automotive storage tasks streamlined with UFS 4.1 Chip Technology
Kioxia, a world leader in memory solutions, has announced the launch of its UFS 4.1 family of embedded flash memory devices. This new technology is designed to address the growing storage demands in the automotive sector, particularly for AI-driven systems, telematics, and advanced driver-assistance systems (ADAS).
Key Features and Benefits
The UFS 4.1 devices offer significant improvements in speed, compatibility, and advanced technology integration. Compared to Kioxia’s previous UFS 3.1 generation, UFS 4.1 devices deliver approximately:
- 2.1× faster sequential read speeds
- 2.5× faster sequential write speeds
- 2.1× faster random read speeds
- 3.7× faster random write speeds
These enhancements support a more responsive and efficient user experience in data-intensive automotive environments.
The devices are available in 128 GB, 256 GB, 512 GB, and 1 TB capacities, making them suitable for a wide range of automotive applications. They are compliant with JEDEC’s UFS 4.1 specification and backward compatible with UFS 4.0 and UFS 3.1 standards, ensuring broad compatibility across current and future automotive systems.
Advanced Technology and Automotive-Grade Robustness
Powered by Kioxia’s 3D flash-memory technology, BiCS Gen 8, the UFS 4.1 family utilizes the CMOS directly Bonded to Array (CBA) technology, enabling higher power efficiency, performance, and density. The devices also employ an in-house designed controller optimized for automotive needs and the MIPI Alliance’s M-PHY version 5.0 interface, supporting up to 4.2 GB/s bandwidth and enabling full-duplex operation.
The UFS 4.1 chips meet AEC-Q100/104 Grade 2 standards, supporting operation at case temperatures up to 115°C, suitable for harsh automotive environments. They also feature enhanced diagnostic capabilities, including vendor-specific device health descriptors for improved device status monitoring and predictive maintenance.
Performance Optimizations
The UFS 4.1 devices support WriteBooster-related extensions like WriteBooster Buffer Resizing and Pinned Partial Flush Mode, providing better flexibility and sustained optimal write performance.
Meeting the Demands of Emerging Automotive Applications
The combination of elevated speed, advanced flash memory technology, automotive-grade reliability, backward compatibility, and enhanced diagnostics positions Kioxia’s UFS 4.1 devices as a compelling solution to meet the demanding storage requirements of emerging automotive applications involving AI, telematics, and advanced driver-assistance systems.
