SEOUL, November 11 (AJP) - Despite the headlines, memory chips do more than power data centers. SK hynix, the frontrunner in high-bandwidth memory (HBM) for AI, is expanding its push into low-power chips for robots, self-driving cars and smart factories as artificial intelligence moves into the physical world.
The South Korean chipmaker said Wednesday it had secured two international certifications covering industrial functional safety and automotive cybersecurity, strengthening its credentials to supply memory for machines where a malfunction could have consequences far beyond a computer crash.
The move broadens its AI memory ambitions beyond the lucrative HBM chips used alongside AI processors in data centers to so-called physical AI — systems that sense, interpret and act on their surroundings.
At the center of that push is LPDDR5X, a low-power DRAM technology widely associated with smartphones. Its ability to process large volumes of data within tight power and heat limits also makes it relevant to autonomous machines.
SK hynix said its LPDDR5X had obtained Safety Integrity Level 3 (SIL 3) certification under IEC 61508, an international standard for industrial functional safety. The company also secured certification for its cybersecurity management system under ISO/SAE 21434, which governs automotive cybersecurity.
Both assessments were conducted by global certification body SGS-TÜV Saar, involving SGS Korea and SGS Japan.
The industrial safety certification covers the LPDDR5X product and its development processes. The cybersecurity certification assesses procedures for managing threats and vulnerabilities throughout product development and production.
The distinction matters because robots and autonomous vehicles use memory to store and transfer sensor readings, AI computation results and control data for real-time decisions. An error that crashes a smartphone application could pose a physical safety risk in a robot working beside people or a vehicle navigating traffic.
SK hynix said its LPDDR5X was designed and validated to support continuous-mode operation under IEC 61508, allowing safety functions to operate while a system remains running. The company described SIL 3 as the highest level attainable for a single memory semiconductor.
The certifications add to its existing automotive credentials. In January, SK hynix obtained Automotive Safety Integrity Level D (ASIL-D) certification under ISO 26262 for its LPDDR5X automotive DRAM. ASIL-D is the highest safety integrity level under that standard.
The company also secured TISAX, an automotive industry information security assessment, in early 2025.
Together, the credentials address requirements that increasingly shape purchasing decisions by automakers, industrial equipment suppliers and robotics developers.
HBM delivers enormous bandwidth to AI accelerators. LPDDR5X addresses the power, space and heat constraints of devices that process AI workloads locally. In those markets, suppliers must demonstrate that their chips and development processes can meet the reliability demands of machines operating around people.
SK hynix faces competition on that front.
U.S. rival Micron Technology has also secured IEC 61508 SIL 3 certification for LPDDR5X memory, according to its published technical materials. Micron says its industrial memory supports continuous-mode operation for safety-critical applications including robotics and factory automation.
In April 2024, Micron also announced that its automotive-grade memory and storage products, including LPDDR5X, had been qualified for Qualcomm Technologies’ Snapdragon Digital Chassis platforms. Such qualifications can help memory suppliers establish a foothold in automotive computing through relationships with processor and platform developers.
SK hynix said it plans to broaden its global customer base among Tier 1 automotive suppliers — companies that supply automakers directly — while targeting robotics platforms, edge AI devices and smart factories.
Its latest cybersecurity assessment covered threat responses, security requirements, product design, validation and vulnerability management. The certification demonstrates that those management processes have been assessed against international standards; it does not guarantee that products are free of cybersecurity risks.
The commercial test is whether the credentials lead to additional design wins and supply contracts. SK hynix has not disclosed new robotics customers, contract values or a revenue timetable directly tied to the certifications.
The company nevertheless sees safety and security as part of its “full-stack AI memory” strategy, extending its role into the reliability requirements of entire AI systems.
"As the physical AI market develops, it is becoming increasingly important to incorporate safety and security frameworks that comply with international standards into the memory development process," said Jonghwan Kim, vice president and head of DRAM development at SK hynix.
"Leveraging our proven safety and security capabilities validated across the automotive and industrial sectors, we will solidify our leadership in full-stack AI memory at the AI system level in physical AI markets, encompassing robotics, edge AI, and autonomous driving."
