SK Hynix has officially proven its core memory competitiveness in the autonomous driving and SDV era, strengthening its future mobility memory strategy.

SK Hynix announced on the 19th that it has obtained ASIL-D (Automotive Safety Integrity Level D) certification, the highest level of the international automotive functional safety standard ISO 26262, for its latest LPDDR5X automotive DRAM.

ASIL-D is the highest level of functional safety required for autonomous driving control systems that are directly related to human life, and is awarded by global certification agency TUV SUD after comprehensively evaluating the entire development, design, verification, and quality system.

With this certification, SK Hynix has been officially recognized for its technological prowess in meeting high performance, low power consumption, and high reliability requirements in the automotive memory market.

In particular, the company has strengthened its position as a key memory company in the future mobility era by securing the stability of large-scale data processing and error minimization capabilities required in autonomous vehicles and SDV (Software Defined Vehicle) environments.

SK Hynix's ASIL-D certified LPDDR5X automotive DRAM meets the performance standards required for next-generation automotive electronic systems such as ADAS, autonomous driving systems, and vehicle infotainment.
/> It maintains stable data reliability even in harsh environments such as extreme temperatures and vibrations, and is characterized by the application of safety mechanisms such as failure notification, self-diagnosis, and repair functions from the design stage.

As automotive electrification accelerates, the competitiveness of automotive memory has become more than just performance; securing functional safety has emerged as a key indicator.

Accordingly, design capabilities that predict and control the possibility of failure in advance are becoming a key differentiating factor in the automotive memory market.

TUV SUD comprehensively reviewed SK Hynix's LPDDR5X products, including safety architecture and design concepts, error prevention, detection, and diagnosis mechanisms, development and verification processes, and quality management systems.

As a result, SK Hynix's development, verification, and quality processes were evaluated to meet global automotive industry standards.

Based on this certification, SK Hynix plans to continue providing high-reliability memory solutions that customers can use with confidence in the autonomous vehicle and future mobility sectors.

As the proportion of electrical and electronic systems in automobiles exceeds 40%, system reliability has become a key factor directly related to passenger safety. Accordingly, ISO 26262 functional safety certification has become a requirement rather than an option.

ASIL, a core indicator of ISO 26262, assigns grades from A to D by combining three elements: Severity, Exposure, and Controllability.

While general instrument panels require ASIL-B level, autonomous driving control systems require ASIL-D, the highest level.

SK Hynix proactively responded to these market demands by building a lineup of automotive DRAMs based on LPDDR5X and completing ASIL-D certification in a timely manner.

To achieve ASIL-D, SK hynix established a functional safety system capable of controlling both systematic and accidental faults. These include a standardized development and verification process based on Functional Safety Management (FSM), a fault management system that meets international standards such as SPFM, LFM, and PMHF, data error correction based on ECC (Error Correction Code), redundant fuses for repair, and fault notification and diagnostic functions. These features were applied from the design stage to meet the stringent standards required by ASIL-D.

With this ASIL-D certification, SK Hynix has proven that its automotive memory business strategy is evolving in the right direction. By securing functional safety certification, a key consideration for product adoption by global automakers, SK Hynix has secured a crucial competitive edge in expanding the automotive memory market and strengthening customer trust.

SK Hynix plans to continue to grow into a key memory company leading the future mobility era based on greater stability, advanced technology, and thorough quality.
