With the rise and widespread application of Artificial Intelligence (AI) technology, apart from the popular autonomous driving systems in the automotive market, a significant number of software-defined automotive systems are also experiencing rapid growth. These software-managed systems create new passenger and driving experiences. Behind these cutting-edge smart solutions, primary concerns about AI revolve around "information security and cybersecurity" protection, thereby catalyzing the rapid adoption of the secure flash memory.
Macronix faced an urgent need to meet memory security requirements for automotive and industrial control electronic data, to ensure confidentiality, integrity, and availability. To address this, they developed the ArmorFlash series of secure flash memory solutions. These solutions include key establishment, encryption, decryption, authentication, and anti-tamper functions. Additionally, a true random number generator is integrated into the memory chips for secure ID or key configurations. ArmorFlash supports various security functions such as identity authentication, crypto key, and secure-boot mechanisms. The ArmorFlash series has received recognition from international autonomous-driving and microcontroller unit (MCU) chip giants, and has earned accolades such as the Taiwan Excellence Award.
The ArmorFlash MX78 series fully complies with ISO/SAE 21434 Information Security Standard Certification
The ISO/SAE 21434 Standard was officially released at the end of August 2021, covering the entire vehicle lifecycle and emphasizing the requirements for cybersecurity risk management. Macronix promptly formed a project team to intensively prepare for the ArmorFlash MX78 series' standard certification, first passing TARA verification activities to assess various scenarios in which threats occur and determine solutions when encountering information security attacks. They also obtained the ISO/SAE 21434 threat analysis and risk assessments (TARA) verification report on June 2022, subsequently achieving full ISO/SAE 21434 Information Security Standard Product Certification in 2024, which marked a significant milestone in cybersecurity design.
The enhanced data access performance of ArmorFlash enhances brand customer user experience
Dr. Donald Huang, director of product marketing at Macronix, emphasized in an interview that advancements in AI applications, such as AI, edge computing, 5G and autonomous driving, are leading to exponential growth in data volume, thus driving the demand for memory. With AI applications increasingly capable of operating independently on multiple terminal devices and personal electronics, secure flash memory plays a crucial role in enhancing system security.
To enhance user experience, the third-generation ArmorFlash MX78 series has been redesigned with a renewed focus on the speed of accessing data. It currently operates more than one hundred times faster than the previous generation of ArmorFlash. This enhancement significantly aids electronic devices in smoothly executing critical security functions during startup, thereby improving overall user operational experience. In an era where speed is paramount across various applications, the access speed of secure memory undoubtedly plays a crucial role in maintaining optimal brand reputation and product quality.
Additionally, ArmorFlash's integrated design consolidates all security functions into a single memory chip, meeting critical security certification standards. This contrasts with typical practices whereby chip manufacturers require additional security chips for specific certifications. Furthermore, ArmorFlash uses a standard Serial Peripheral Interface (SPI) that is pin-to-pin compatible with standard NOR Flash SPI or OctaBus interfaces, unlike products using proprietary interfaces. By integrating the standard SPI interface into a single-chip design, ArmorFlash significantly reduces design complexity for engineering teams. This approach not only enhances product performance but also accelerates volume production and time-to-market, providing a competitive edge in seizing valuable market opportunities.
ArmorFlash earns favor from leading global automotive OEMs, automotive electronics manufacturers, and industrial control giants
Since 2019, Macronix's first-generation ArmorFlash has been integrated within NVIDIA's Level 2+ to Level 5 autonomous driving systems, including the DRIVE AGX Xavier and AGX Pegasus autonomous vehicle computing platforms. By leveraging robust secure memory capabilities, ArmorFlash has strengthened data security in autonomous systems and enhanced driver safety.
The second and third generations of the ArmorFlash MX78 series have now achieved ISO/SAE 21434 standards, putting focus on "cybersecurity" design. This accomplishment has facilitated Macronix's memory products to secure significant partnerships with major international autonomous driving solution providers and automotive MCU chip manufacturers, as well as adoption by leading automotive and automotive electronics manufacturers.
Beyond the automotive sector, ArmorFlash chips are also employed in industrial control and embedded application systems, such as Japan's Renesas Electronics RA series of MCUs. By utilizing ArmorFlash chips featuring integrated hardware encryption accelerators, cybersecurity is bolstered, and more secure and dependable network connections across various embedded applications are ensured.
In addition to the aforementioned technologies, ArmorFlash also offers a physical unclonable function (PUF), which functions similarly to chip biometrics with a fundamental encoding method. This equips the chip with a chip fingerprint capability, providing memory chips with unique, unpredictable physical characteristics and non-replicable key features. These properties offer high-level encryption and are applied in various information security and confidentiality applications.
Huang emphasized that the identification and prevention of potential information security and cybersecurity threats is an ongoing pursuit. Macronix has already obtained automotive information security standard certifications but continues to reinforce efforts at every stage, from product design and development to volume production and market launch. This ongoing effort aims to identify potential threats and security vulnerabilities, establishing a common foundation for cybersecurity risk management. The newly launched ArmorFlash MX78 series of flash memory solutions significantly shortens the time to market for customers' products, meeting the urgent needs for the automotive, industrial control, and embedded application markets. Through ArmorFlash technology, Macronix is in a strong position to expand its international market presence and continue collaborating with global customers to sustain its success.
