Unique advantages:

1. Completely independent intellectual property rights, continuous supply guarantee for the entire product line Deyi Microelectronics is the only company in China that has the ability to self-develop automotive-grade eMMC master chips and can mass-produce automotive-grade eMMC. Its automotive-grade eMMC is equipped with a self-developed eMMC master chip, which can provide end-to-end data protection. It is equipped with a high-performance error correction engine to achieve high efficiency and low power consumption, which can effectively extend the service life of eMMC and improve stability. At the same time, based on the self-developed automotive-grade storage master chip, the company is about to launch automotive-grade BGA SSD and UFS products to meet the growing and diverse storage needs of the automotive industry and continue to provide stable and reliable supply guarantees.

2. All-round customization capabilities. Deyi Microelectronics relies on its self-developed storage controller and customized firmware algorithm to realize a variety of customized solutions such as storage partitioning, full disk pre-burning, built-in SR-IOV, data integrity protection, encryption destruction, intelligent temperature control, and super durability, creating a storage solution that truly meets the needs of automotive customers.

3. Quality analysis and screening capabilities for automotive-grade Flash particles Create highly reliable and robust eMMC storage chips Deyi Microelectronics has been conducting reliability tests based on various system storage control technology platforms and customer application platforms for a long time, and has rich experience in NAND Flash storage particle characteristic analysis and research. Combined with comprehensive analysis and judgment of factors such as Flash particle temperature, erase and write times, data retention, read and write performance, and data interference, the Flash parameters are tuned or screened according to product requirements, and finally a highly reliable and robust eMMC storage chip is created.

4. High reliability product verification, strict quality control system Deyi Microelectronics' automotive-grade eMMC storage chip has passed the automotive test verification of the International Automotive Electronics Association AEC-Q100 Grade 2, and can operate stably in extreme scenarios from -40℃ to +105℃, ensuring the reliability and stability of the product. From the initial design, testing and verification of the product, we strictly follow the JEDEC specifications, and strictly carry out reliability tests such as high and low temperature aging, high and low temperature storage, data read interference test, temperature cycle, and durability test in accordance with the AEC-Q100 requirements, to ensure the quality requirements of automotive customers in a long-term and stable manner.

5. Extensive market application and full localized service. Multiple automotive-grade eMMC storage chips of Deyi Microelectronics have been mass-produced in mainstream automobile brands such as Dongfeng, Changan New Energy, SAIC Maxus, and Shaanxi Automobile, and are widely used in automotive front-end systems, including digital instruments, T-Box, ADAS, smart cockpits, in-vehicle infotainment systems, event recorders and other key areas.

Application scenarios:

Deyiwei's automotive-grade eMMC memory products are widely used in automotive front-end system applications including digital instruments, T-Box, ADAS, smart cockpits, in-vehicle infotainment systems, event recorders, etc.

Future prospects:

With the deepening of the new "four modernizations" of smart cars and the explosive development of new energy vehicles, the demand for computing power and storage power of various components of smart cars, especially new energy vehicles, is increasing day by day. With the continuous improvement of the level of automobile intelligence and the continuous expansion of on-board memory and storage capacity, the application of automotive eMMC is relatively fast, becoming the largest storage product in the current automotive market. The development of autonomous driving technology, especially the application of large AI models, will greatly increase the demand for storage capacity. More data will be stored and processed locally in the vehicle, and a large amount of data needs to be processed and responded to quickly, which requires storage chips to have larger capacity, higher bandwidth and faster read and write speeds. The continuous innovation of storage technology has shifted from eMMC to UFS, and is expected to adopt PCIe SSD to meet the growing demand for automotive data storage and processing. With the rapid development of the domestic automobile market, domestic storage suppliers are accelerating the layout of on-board storage products, and are expected to achieve technological breakthroughs and market substitution in the field of automotive-grade storage chips. As major domestic automakers pay more and more attention to the local supply chain system, Deyiwei, as a domestic automotive storage manufacturer with independent intellectual property rights, has successfully laid out a full product line including automotive-grade eMMC, UFS, BGA SSD, etc., and will have huge potential and broad market space in the automotive market.
