Micron UFS 4.1 memory

Architected to power AI workloads, Micron’s latest automotive solution, built with G9 NAND, equips the industry to create safer, smarter more connected driver experiences. Micron UFS 4.1 for automotive is the world’s first UFS 4.1 automotive solution built with G9 NAND, setting a new industry standard for intelligent vehicle storage. Engineered for advanced AI-driven systems, it delivers outstanding speed, reliability, and safety, with ASIL-B compliance, ASPICE certification, robust cybersecurity, and enhanced thermal protection.

Delivering bandwidth of 4.2GB/s - double that of its predecessor - the company’s automotive UFS 4.1 accelerates data access for AI models, enriching the in-cabin experience by powering features such as voice assistants, personalized infotainment and advanced safety alerts. This bandwidth in advanced driver assistance systems (ADAS) and autonomous vehicles also enables rich data capture from cameras, lidar and radar sensors to upload and feed AI model retraining and enhancement in the data center.

Key features

• Turbocharged read and write speeds: UFS 4.1’s bandwidth offers accelerated sequential read speeds for rapid data access for AI. Enhanced write speeds enable ultra-fast data logging for ADAS models, supporting refinement of perception and decision-making algorithms. UFS 4.1’s high read performance can enable use cases such as rapid switching between GenAI models for in-cabin experiences, allowing system designers to store multiple models while reducing memory requirements - all while providing a low-latency user experience and optimizing costs.
• Fast boot times: Thanks to Micron’s G9 technology and proprietary firmware, the firm’s UFS 4.1 offers 30% faster device boot and 18% faster system boot. These boot times enable intelligent systems to rapidly come online when the ignition is engaged, delivering more responsive cockpit experiences.
• Ultra-high endurance: The company’s automotive UFS 4.1 offers up to 100,000 program/erase (P/E) cycles for single-level cell mode and 3,000 program/erase cycles for triple-level cell mode, providing the necessary endurance for automotive applications where vehicles may operate for years with millions of write operations from lidar, radar and cameras.
• Extended thermal protection: Engineered for harsh vehicle environments, UFS 4.1 provides thermal protection and consistent high performance from -40°C up to 115°C case temperature - extending beyond JEDEC’s standard 105°C to provide manufacturers the opportunity to reduce thermal cooling footprints without compromising reliability for mission-critical autonomous driving.
• Advanced host features: The solution offers advanced UFS 4.1 features, including a host-initiated defragmentation feature that leverages advanced algorithms to optimize data workloads for defragmentation to provide fast performance, especially during high-demand periods.
