Upgraded Storage Solution in Autos: UFS 4.1 Chip Takeover for Vehicle Duties
Kioxia, a world leader in memory solutions, has unveiled its new UFS 4.1 family, designed specifically for use in cars and other transportation applications. This latest offering from Kioxia America meets the demands of the evolving automotive landscape, delivering significant performance improvements and automotive-grade reliability.
Performance Boost for Next-Generation In-Vehicle Systems
The Kioxia UFS 4.1 chips more than double the speed compared to prior versions, offering faster sequential and random read/write speeds. For instance, sequential read and write speeds are improved by 2.1x and 2.5x, respectively, over UFS 3.1 [1][3][4].
Key Features
The Kioxia UFS 4.1 family complies with the JEDEC UFS 4.1 standard, boasting backward compatibility to UFS 4.0 and 3.1. It employs the MIPI M-PHY v5.0 interface for a bandwidth of 4.2 GB/s [1][5]. The chips also leverage Kioxia’s generation 8 BiCS FLASH 3D flash memory and in-house designed controller, enhancing storage density and reliability [1][3][4][5].
To cater to automotive-specific standards, these chips meet AEC-Q100/104 Grade 2 and support operation in harsh environments up to a maximum case temperature of 115°C, ensuring durability in automotive conditions [1][3][4]. The UFS 4.1 family also supports full-duplex operations, enhancing data throughput for demanding applications like AI-based Advanced Driver Assistance Systems (ADAS), infotainment, telematics, and vehicle domain controllers [1][3][4].
Advanced Diagnostic Features and Extensions
The Kioxia UFS 4.1 chips come with enhanced diagnostic features such as vendor-specific device health descriptors for easier device monitoring and predictive maintenance, which improve system reliability and reduce downtime [5]. They also support advanced UFS 4.1 extensions including WriteBooster Buffer Resizing and Pinned Partial Flush Mode, allowing better performance flexibility and optimized write efficiency [5].
Benefits for Automotive Applications
The Kioxia UFS 4.1 chips cater to the increasing demands for storage and compute power driven by AI models, telematics, and driver/passenger monitoring systems [1]. They provide more responsive user experiences in data-intensive environments with faster read/write capabilities [3][4]. Moreover, they ensure robust, reliable operation under automotive conditions, critical for safety and longevity of in-vehicle systems [1][3].
Flexible Storage Options
Kioxia offers these UFS 4.1 chips in capacities from 128 GB up to 1 TB, enabling flexible storage options tailored to various automotive and transportation use cases [1][3][4].
