SK hynix said its LPDDR5X DRAM has received Safety Integrity Level 3 certification under IEC 61508, the international standard for industrial functional safety, plus Cybersecurity Management System approval based on ISO/SAE 21434, the company announced. Financial News reported the same certifications on Nov. 11, saying both followed assessments by SGS-TÜV Saar.
Why it matters: SK hynix said SIL 3 is the highest level a single memory semiconductor can reach on the standard’s four-level scale, and that the LPDDR5X was designed and validated for continuous-mode operation, in which safety functions must run in real time without stopping the system — a foundation, it said, for uses such as real-time robot control. Financial News also reported that the certification covered both the product and its development process.
The company said the industrial certification builds on ISO 26262 ASIL-D automotive functional-safety approval obtained in January, and on TISAX information-security certification it said it was first in the memory industry to receive last year. Financial News quoted Kim Jong-hwan, vice president and head of DRAM development, as saying safety and security frameworks “are becoming increasingly important in the memory development process” as the physical AI market develops.
SK hynix said it plans to target customers building robot platforms and systems-on-chip, and Financial News said the company also wants to expand into autonomous-driving platforms, software-defined vehicles, edge AI and smart factories.
