What is eMMC?
Characterized as a storage solution for a wide range of embedded systems, eMMC Storage finds its usage in consumer electronics, handheld computers, smart home appliances, tablets, smartphones, GPS systems, eReaders, IoT, automotive embedded applications and other industrial uses. Embedded MultiMediaCard (eMMC) is an embedded non-volatile NAND flash memory system consisting of the MMC (multimedia card) interface, flash memory and a flash memory controller, which simplifies the application interface design and frees the host processor from low-level flash memory management.
Why is eMMC used in the automotive industry?
eMMC Storage is offered in small BGA (Ball Grid Array) packages which need to be soldered to the board and consume low power in the absence of a constant power source, making it a viable, low-cost memory solution for space-constrained automotive industry applications. The benefits of the non-volatile memory interface design and qualification process of the eMMC aid automotive electronics resulting in a reduction in time-to-market and facilitating support for future eMMC applications. The trend of incorporating Artificial Intelligence in the automotive industry necessitates lower latency rates, optimized performance and adequate storage of web-based data guaranteed by the eMMC. Advanced driver-assistance system (ADAS) prevalent in autonomous automobiles expands their footprint by utilizing the eMMC due to their high-density flash performance. ADAS is the facilitator of adaptive cruise control, automatic lane centering and collision avoidance technologies. The light distance and ranging (LiDAR) system is a prominent ADAS technology that utilizes eMMC for real-time image recognition and helps the vehicle navigate the surrounding environment. Global Automotive Electronics Market demand is anticipated to be valued at $300,332.43m in 2022, forecast to grow at a CAGR of 7.30% to be valued at $607,574.4m from 2022 to 2032. Cars are becoming much more than just modes of transportation with the automotive industry increasingly employing eMMCs due to their smaller footprint, low-power consumption and cost-effectiveness in various cutting-edge applications and workloads such as:
FLEXXON bids a storage solution for the Automotive Industry: THE eMMC!!!
Remarkable Features of FLEXXON’s eMMC beneficial for the automotive industry:
- Tailor-made firmware: The firmware warrants the use of eMMC according to the nature of the automotive application.
- Highly Integrated eMMC Solution: Exceptional storage capacity of 4GB to 512GB supports an extensive temperature range of -40°C~105°C for automotive applications.
- Packaged Design: Compact-sized storage device to meet various automotive industries’ high reliability and high-performance needs.
- Pre-loaded data integrity in the reflow process: Data integrity refers to the reliability and accuracy of automotive data. The eMMC pre-loaded automotive data might get corrupted during soldering. FLEXXON’s eMMC uses pSLC blocks only during the soldering process to ensure no data is lost during reflow.
- Static and Dynamic Wear Leveling: FLEXXON’s eMMC supports static and dynamic wear leveling. The static wear leveling shifts cold automotive applications data (seldom updated system data) to the block of the maximum erase count in the data area, whereas the dynamic wear leveling shifts hot automotive data (constantly updated user data) to the block of the minimum erase count in the data area. Hence, reducing the risk of read disturb and sustaining data integrity for the automotive industry.
- Auto Read Refresh: Auto Read Refresh monitors the bit errors in every read operation of eMMC. This is important for read-intensive automotive applications. To prevent data damage in eMMC, refresh operation will be triggered when the bit errors are approaching the threshold.
- Power Loss Protection: FLEXXON’s eMMC supports pSLC Area Backup Technology for automotive applications. Partial NAND is enabled as pSLC to backup data. The pSLC area is non-volatile storage that can provide higher read/write performance, endurance and data reliability. FLEXXON’s eMMC endorses UECC handling which in case of sudden power loss, initiates an uncorrectable ECC found in a programmed page. The eMMC will scan the whole system blocks, and once an ECC uncorrectable or higher ECC error bit is found, those pages will be discarded, and the valid data will be moved to a health block. The FLEXXON’s eMMC disseminates a power-off notification to provide sufficient time for the device to back up all the cache data.
- Advanced NAND management: RoHS Compliance ensures superior quality NAND management, and controlled BOM provides consistent performance of the automotive applications.
- SMART: FLEXXON’s eMMC supports the Linux command to read the SMART information and monitor the health and remaining life of the eMMC installed in the automotive applications to avoid critical failures.
