SK hynix said on 11 November 2026 that LPDDR5X and its development process received IEC 61508 SIL 3 certification, which the company calls the highest level a single memory chip can reach, plus an ISO/SAE 21434 cybersecurity management certification. Both came from SGS-TUV Saar. The company says the part was validated for continuous mode, for uses such as robotics and smart factories, and that this extends an earlier ISO 26262 ASIL-D automotive certification. The Asia Business Daily reported the same claims.
