With the high attention of the world to independent and controllable technology and domestic "domestic substitution". With the steady advancement of the strategy, memory chips, as the core components of information systems, have become one of the key technologies for the country's key development. In this context, BIWIN Storage has successfully broken through with two iconic products, the 100% localized power exclusive eMMC and the domestically produced and self-developed vehicle-grade eMMC, demonstrating the strong strength of China's storage industry. This not only marks the maturity and implementation of BIWIN's technical route, but also provides an example for the application of domestic high-reliability storage in key fields.
Ⅰ Electricity exclusively for eMMC: domestic storage escorts the "infrastructure of the country".
At the 50th China Electrical Instrumentation Industry Development Conference held in Changzhou, Jiangsu Province on April 14, BIWIN Storage officially released its eMMC memory chip for the power industry. According to official information, the product is designed with domestic chips and independent firmware algorithms, covering the capacity range of 8GB to 128GB, and supporting an industrial wide temperature range of -40°C to 105°C, with a P/E (erase) life of more than 30,000 times, which can effectively meet the demanding requirements of the power industry for high reliability, long life cycle and extreme environmental adaptability.
Power systems typically operate in outdoor, unattended, and high-frequency data writing environments, which put forward extremely high standards for the reliability, security, power consumption control, and power-down protection mechanisms of memory chips. BIWIN's eMMC has multiple technical guarantees including power-down protection, pSLC mode, redundant data verification, etc., which can still operate without data loss and uninterrupted system under extreme conditions such as sudden power failure, sudden temperature change, and instantaneous voltage fluctuation.
In particular, it is worth mentioning that BIWIN has deeply optimized the compatibility of the protocol stack with the firmware of terminal equipment in the power industry through self-developed master control algorithms, so that it has lower latency and higher real-time performance in "small packet frequency writing" scenarios such as current fluctuation records, fault logs, and operation logs, and improves the stability and efficiency of the power data acquisition and recording system.
Industry experts pointed out that the informatization of the power industry is entering the deep water area, and traditional general-purpose storage products have been difficult to meet the needs in terms of stability and data fidelity. The domestic eMMC launched by BIWIN has performed well in technical indicators and application measurements, and it has entered the trial stage in the power grid test system and intelligent distribution terminal in many places in China, and has received good feedback, which is expected to gradually replace imported products and become the "core storage force" of the domestic power system.

ⅡAutomotive-grade eMMC: Fully localized, benchmarked against international automotive-grade standards
At the 2025 Shanghai International Automobile Industry Exhibition, which opened on April 23, BIWIN brought its domestically produced and self-developed automotive-grade eMMC products to the show, and announced that the series of products have passed AEC-Q100 Grade 2 certification, supporting a wide operating temperature range of -40°C to +105°C, meeting the stringent requirements of mainstream automotive electronics platforms for automotive-grade storage.
With the rapid development of autonomous driving, intelligent cockpit, V2X Internet of Vehicles and in-vehicle multimedia systems, automobiles have put forward new performance requirements for memory devices: they must not only have large capacity and high-speed transmission capabilities, but also ensure stable operation in long-term high-temperature environments. BIWIN's automotive-grade eMMC covers the capacity range from 16GB to 128GB, and has a built-in self-developed intelligent error correction algorithm (ECC) and health status management mechanism to ensure uninterrupted on-board data processing and a very low failure rate.
It is worth mentioning that the design of automotive products is not only about the high reliability of the device, but also about the stability of the supply chain and the controllability of the life cycle. Through the completely domestic device combination, BIWIN has broken the "bottleneck" situation of dependence on imports for key storage, and provided an alternative path for host manufacturers and Tier 1 suppliers to be independent, controllable, cost-effective, and fast response.
According to a report released by market research firm Yole Group, the global automotive-grade eMMC market is growing rapidly and is expected to reach more than $1.5 billion by 2027. Driven by the rapid development of domestic new energy vehicles and intelligent connected vehicles, the demand for local high-reliability storage solutions in the Chinese market will also usher in a multi-fold expansion. BIWIN's domestically produced products will significantly enhance the control of domestic OEMs over on-board systems, and provide practical support for the implementation of domestic substitution in the industry.
Ⅲ Industrial synergy: a collaborative model of China's storage industry chain
BIWIN's breakthrough in pure localization is not alone, but based on the deep integration and collaborative innovation of China's storage industry chain. In the R&D process of eMMC for electric power, BIWIN has united with NAND flash memory suppliers, main control chip design companies, firmware algorithm R&D units, wafer foundries and packaging and testing service providers to complete the whole process of localization and closed-loop from underlying architecture design, tape-out manufacturing to final packaging and testing.
In the development of automotive eMMC, BIWIN also works closely with system integrators, on-board platform manufacturers, and sensor designers in the domestic automotive electronics supply chain to gain an in-depth understanding of the specific needs of storage characteristics in various application scenarios, and ensure that the product design meets the standard requirements of "high consistency, traceability, and safety redundancy" of vehicle manufacturers.
Behind this is China's continuous investment in the cultivation of the independent semiconductor industry chain in recent years. The national and local governments have continuously lowered the threshold for the implementation of domestic technologies through industrial funds, R&D subsidies, certification channels, etc., so that local enterprises with system-level product design capabilities like BIWIN can quickly iterate products, obtain industry recognition, and complete commercial deployment.
Ⅳ Market outlook: domestic storage ushered in an "acceleration period" of development
According to data from IC Insights, Omdia and other institutions, the global storage market size has rebounded to more than $160 billion in 2024, and the average annual growth rate is expected to exceed 12% in the next three years. In this context, domestic storage manufacturers are facing unprecedented opportunities.
In terms of the power market, the State Grid's "New Digital Infrastructure" plan promotes the upgrading of key node equipment such as smart substations, distributed power sources, and charging and swapping facilities, and the demand for highly reliable and high-durability storage devices has increased sharply. BIWIN Power's exclusive eMMC is just suitable for this kind of application scenario and has the application conditions for large-scale deployment.
In terms of the automobile market, China's new energy vehicle sales will exceed 9.5 million units in 2024 (according to the China Passenger Car Association), accounting for nearly 60% of the global total. Driven by the trend of "new three modernizations" (intelligence, electrification, and networking), the amount of on-board data and storage intensity have been greatly improved, and domestic vehicle specification storage has ushered in a golden window period. BIWIN's automotive-grade eMMC adapts to mainstream platform solutions (such as SoCs such as Qualcomm, MediaTek, Horizon, and Black Sesame), and has started the verification process in a number of leading new energy vehicle brands, and the market potential is promising.
Ⅴ Facing challenges and ways to break the game
Despite the remarkable achievements, BIWIN still faces a number of challenges:
There is still room for improvement in product performance compared with international giants. For example, in terms of read and write speed, NAND flash memory particle maturity, and packaging density, there is still a gap with international giants such as Samsung, Kioxia, and Micron.
The certification cycle of the vehicle specification market is long and the entry threshold is high. OEMs have a long verification cycle for product stability and have extremely strict requirements for suppliers.
Brand influence and channel expansion still need to be strengthened. Although the products have reached international standards, in some overseas markets and high-end projects, stronger market expansion capabilities and brand endorsement are still needed.
In this regard, BIWIN's coping strategy has gradually become clear: on the one hand, it has increased investment in core technology modules such as main control chips, self-developed firmware, and AI cache scheduling, and promoted the in-depth iteration of eMMC, UFS, SSD and other products; On the other hand, strengthen cooperation with scientific research institutions, standards organizations, and certification bodies, promote the establishment of a domestic storage standard system, and accelerate the international layout, and give priority to the implementation in emerging markets such as the "Belt and Road".
Ⅵ Conclusion: Build a "core" foundation for the core industry
The two domestic eMMCs launched by BIWIN Storage are the achievements of its more than ten years of deep cultivation of embedded storage, and also represent the key nodes of China's storage technology from "following" to "running". Whether it is the core of infrastructure such as the power system or the frontier of high-end applications such as automotive electronics, BIWIN is writing the rise of "China's storage can be replaced, landed and trusted" with practical actions.
In the future, as more local companies like BIWIN continue to deepen their efforts in technological innovation and industrial collaboration, China is expected to play an increasingly important role in the global semiconductor ecosystem, realizing the industrial leap from "lack of core and less soul" to "core self-improvement".
