汽车级UFS 3.1 brings the latest smartphone performance to your car

美光科技| 2021年6月

我们都知道该怎么做.

我们去年才买的最新款, 最好的智能手机, 但今天，下一代手机发布了. 它有一个更大的, brighter screen using the latest organic LED (OLED) technology, 为所有应用程序提供更多内存, 但最重要的是, 它有最新的, fastest processor and memory that deliver an almost instantaneous user experience. In fact, the average smartphone today is more responsive and more user friendly than most computers from just a few years ago.

移动设备及其用户交互

The smartphone experience sets the standard for what consumers expect when interacting with an information device. 当知情的消费者走进他们的车, the expectation is that the interactive experience from their mobile devices should extend to the car. 然而多年来 车内的经验 没有达到那个标准吗. Vehicles historically have had small lower-resolution screens, 缓慢的性能, 以及无法升级的静态特性. Many analyst reviews and consumer ratings underscore these shortcomings.

最新一代IVI更智能

但这一切都在改变! 最新一代 车载信息娱乐系统(IVI) are built on compute platforms that rival those in modern mobile devices, 具有可升级的功能, Android应用商店, 还有最新的高分辨率显示屏. But to date these systems have still lacked one important component that has benefited the mobile industry for the last few years: the inclusion of the latest 通用闪光系统(UFS) 3.1存储设备.

UFS 3.1 devices enable two times faster read performance and a 50% improvement in sustained write performance than 最后一代UFS 2.1 devices, 支持更快的启动和无线更新, more responsive launching of 应用程序 and an overall smoother user experience. (See Figure 1, which is based on expected speeds from JEDEC.) These devices have not been available to the automotive industry until now.

美光最近推出了 UFS 3的第一个汽车合格投资组合.1 .存储设备. These managed NAND components meet the rigors of the automotive environment and bring the benefits of faster performance to automotive IVI systems, bringing the user experience in line with the expectations of consumers. 基于96层NAND技术, this memory is faster than previous generations of NAND, 提供成本/密度优势vs. previous generations while supporting capacities up to 2 TB.

“Car owners increasingly demand their experiences in-cabin to match those of their mobile devices in terms of instant-on, 更多的应用程序和无缝连接,克里斯·巴克斯特说, corporate vice president and general manager of Micron’s Embedded Business Unit. “These feature-rich systems are expected to work a few seconds after the key turns on the ignition; there’s little tolerance for PC-like wait times on the road. With superior performance, Micron’s portfolio of UFS 3.1 automotive storage eliminates lags and continuously powers crisp, 边缘的智能体验.”

UFS 3.1符合高汽车质量标准

In addition to their many performance benefits, Micron UFS 3.1 .存储设备 meet the following automotive standards:

  • 美光的UFS 3.1 products are designed to JEDEC specification, which is the basis for any memory device. Micron automotive memories are also compliant with specific automotive quality and reliability standards, 其中包括Automotive SPICE®, IATF 16949 and AEC-Q104 in addition to support for extended temperature ranges from –40°C to 105°C.
  • 美光的UFS 3.1 solutions support the production part approval process (PPAP) and advanced product quality planning (APQP).
  • 美光的UFS 3.1 products employ a redundant array of independent NAND (RAIN) technology to help protect data inside the UFS device against unexpected errors and ensure best-in-class data integrity.
  • 美光的UFS 3.1 product has been developed under an IATF 16949 compliant Quality Management System (QMS) to provide a level of systematic fault coverage as per ISO 26262 QM definition. Micron provides support to customers who need to integrate its products in their functional 安全应用程序. This support includes Safety Analysis Report, reporting FMEDA results and metrics, and
    • 安全应用说明和引脚FMEA, providing guidelines and instructions for using Micron products in 安全应用程序. 汽车UFS 3.1 .质量依赖于:
    • Micron’s mature automotive development and manufacturing process
    • 需求的评审和检查, 设计规范和实现, 以及在UFS 3期间创建的其他工作沙巴体育结算平台.1 .沙巴体育结算平台开发与生产
    • 详尽的预硅验证, 包括仿真, 设计分析和形式化验证方法
    • 严格的后硅验证, 包括验证, characterization and AEC-Q104 automotive qualification
    • Requirements traceability to pre-silicon and post-silicon verification
    • 最先进的汽车生产测试
    • 定性失效模式分析(Design-FMEA)
    • Quantitative analysis of random hardware faults (FMEDA)
