\n<\/strong><\/div>\n<\/div>\n

As the era of physical AI \u2014 in which AI systems perform physical tasks in the real world \u2014 takes shape, new standards are emerging for memory semiconductors. Robots and vehicles that make autonomous decisions and move independently can cause accidents if they malfunction or fall victim to data breaches. As a result, functional safety, which protects against unintended failures, and cybersecurity, which safeguards against malicious external attacks, have become essential requirements for memory.<\/p>\n

\"\"<\/p>\n

Against this backdrop, SK hynix announced that its LPDDR5X*<\/span> DRAM has obtained Safety Integrity Level 3 (SIL 3) certification under IEC 61508, the international standard for industrial functional safety, as well as Cybersecurity Management System (CSMS)*<\/span> certification based on ISO\/SAE 21434, the international standard for automotive cybersecurity. Both certifications were granted following rigorous assessments by the global certification body SGS-T\u00dcV Saar (involving both SGS Korea and SGS Japan).<\/p>\n

Building on its previously obtained ISO 26262 ASIL-D automotive functional safety certification<\/a>, SK hynix has now extended its functional safety credentials beyond automotive applications to a broader range of industrial applications, including robotics and smart factories, while also validating its Cybersecurity Management System (CSMS) against international standards. Together with the TISAX*<\/span> certification \u2014 a global information security standard for the automotive industry that SK hynix was the first in the memory sector to obtain early last year<\/a> \u2014 these achievements further strengthen the company\u2019s portfolio of international safety and security certifications required by the automotive and physical AI markets.<\/p>\n

Expanding functional safety capabilities across industries with IEC 61508 certification<\/h3>\n
<\/div>\n<\/div>\n<\/div>\n

\"\"<\/p>\n

\u25b2 SK hynix IEC 61508 Product and Process Certificates<\/p>\n

IEC 61508 is an international standard that serves as the foundation for industry-specific functional safety standards. Certification levels are classified into Safety Integrity Levels (SIL) ranging from SIL 1 to SIL 4, with higher levels indicating more stringent requirements. The SIL 3 certification achieved by SK hynix is the highest level attainable for a single memory semiconductor.<\/p>\n

\"\"<\/p>\n

\u25b2 IEC 61508 Safety Integrity Levels (SIL) and operating modes. LPDDR5X supports SIL 3 and continuous mode.<\/p>\n

IEC 61508 evaluates reliability based on how safety functions operate, classifying them into low-demand, high-demand, and continuous modes. SK hynix\u2019s LPDDR5X was designed and validated to support continuous mode, which requires maintaining safety in real time without interrupting system operation. This provides a foundation for applications such as real-time robotics control.<\/p>\n

The significance of this certification lies in the expansion of SK hynix\u2019s functional safety capabilities beyond automotive applications to a broader range of industries, including robotics and smart factories. Since vehicles and robots operate on similar principles of sensing their surroundings, making decisions, and executing control actions, the safety expertise SK hynix has accumulated in automotive applications provides a foundation for expanding into robotics.<\/p>\n

Another notable achievement is that SK hynix secured certification not only for its LPDDR5X product but also for the entire development process behind it. This demonstrates that the company has established a framework for consistently incorporating safety requirements into both current and future products. Leveraging the low-power, high-performance characteristics of LPDDR5X, which make it well suited for edge devices*<\/span> sensitive to power consumption and heat generation, SK hynix plans to actively address the functional safety requirements of customers developing robotic platforms and System-on-Chip (SoC)*<\/span> solutions.<\/p>\n

* <\/span>Edge device: A device that interacts closely with people in everyday life and generates data.
\n* <\/span> System-on-Chip (SoC): A semiconductor chip that integrates multiple functions, such as CPUs, GPUs, and memory, into a single chip.<\/div>\n

Validating cybersecurity across the vehicle lifecycle with ISO\/SAE 21434 certification<\/h3>\n

\"\"<\/p>\n

\u25b2 SK hynix ISO\/SAE 21434 Cybersecurity Process Certificate<\/p>\n

Alongside functional safety, cybersecurity is another critical pillar of reliability. While ISO 26262, which SK hynix obtained in January this year, is a functional safety standard addressing unintended system failures, ISO\/SAE 21434 is a cybersecurity standard designed to protect against malicious attacks. The two standards therefore complement each other. As vehicles evolve toward the software-defined vehicle (SDV)*<\/span> model and become increasingly connected to external communication networks, cybersecurity threats are also increasing. In response, the United Nations Economic Commission for Europe (UNECE)*<\/span> has mandated the establishment of a Cybersecurity Management System (CSMS) as a prerequisite for vehicle type approval.*<\/span><\/p>\n

* <\/span>Software-defined vehicle (SDV): A vehicle connected to external communication networks in which software plays a central role in vehicle operation and control.
\n* <\/span>United Nations Economic Commission for Europe (UNECE): A United Nations body responsible for establishing international safety standards and regulations, including those related to automobiles.
\n* <\/span>Vehicle type approval: A certification process that verifies whether a vehicle or vehicle component complies with the regulations and standards of a specific country or region.<\/div>\n

\"\"<\/p>\n

\u25b2 Cybersecurity management across the product lifecycle as required by ISO\/SAE 21434 and the scope of SK hynix\u2019s certification<\/p>\n

ISO\/SAE 21434 requires cybersecurity activities to be managed at each stage of the product lifecycle, from development and mass production to operation and decommissioning, based on threat analysis and risk assessment (TARA).*<\/span> Through its latest CSMS assessment, SK hynix\u2019s procedures across product development and mass production \u2014 including threat response, security requirements definition, design and validation, and vulnerability management \u2014 were verified as meeting international standards.<\/p>\n

From a memory perspective, this certification is particularly important because autonomous vehicles make decisions and execute control functions based on data stored in and transferred through memory, including sensor inputs, AI computation results, and encryption keys. If this data is tampered with or exposed, the integrity of the entire vehicle system could be compromised. With this certification, SK hynix has met the requirements to supply automotive memory to mobility customers that must establish a CSMS. Following its TISAX automotive information security certification obtained last year, the company has now also completed verification against international standards in the field of cybersecurity.<\/p>\n

A vision for full-stack AI memory in the era of physical AI<\/h3>\n
<\/div>\n<\/div>\n<\/div>\n

SK hynix has secured a comprehensive range of international certifications covering functional safety (ISO 26262 and IEC 61508), cybersecurity (ISO\/SAE 21434), and information security (TISAX). These certifications demonstrate the company\u2019s credentials as a trusted memory supplier for customers in the autonomous driving and SDV sectors \u2014 areas that demand both safety and security.<\/p>\n

Building on these achievements, SK hynix plans to increase its participation in autonomous driving platforms and SDV projects while expanding its global Tier 1*<\/span> customer base. The company also plans to expand the use of its memory products in industrial applications, including robotics, edge AI, and smart factories. Through these efforts, SK hynix intends to strengthen its functional safety and security capabilities across the automotive and industrial sectors, providing reliable memory solutions at the AI system level.<\/p>\n
