SK hynix has obtained industrial functional safety certification for its low-power DRAM LPDDR5X, as well as a vehicle cybersecurity management system certification. This move aims to enhance not only the performance of its memory products but also their safety and security competitiveness in the growing physical AI market, which involves direct control of physical devices like robots and cars by artificial intelligence.
On November 11, SK hynix announced that its LPDDR5X DRAM has received the Safety Integrity Level (SIL) 3 certification under the international standard IEC 61508 for industrial functional safety. The company also secured cybersecurity management system (CSMS) certification based on the international standard ISO/SAE 21434 for automotive cybersecurity. Both certifications were evaluated by the global certification body SGS-TÜV Saar.
IEC 61508 is an international standard that requires industrial equipment to maintain safety functions even in the event of failures or malfunctions. SIL is categorized into four levels, with SIL 3, obtained by SK hynix, representing the highest level achievable by a single memory semiconductor. This product also supports continuous operation mode, maintaining real-time safety without system interruptions.
In the realm of physical AI, where robots and autonomous vehicles make decisions and move in real environments, ensuring functional safety is crucial, as memory errors can lead to safety incidents beyond mere data processing issues.
SK hynix has also broadened its certification scope in the cybersecurity field. ISO/SAE 21434 is a standard for managing cybersecurity risks during the development, production, and operation of automotive electronic systems. SK hynix was recognized for meeting international standards in threat response and vulnerability management throughout its product development and mass production processes.
Earlier this year, SK hynix received the highest automotive functional safety certification, ISO 26262 ASIL-D, in January. Last year, it became the first in the memory industry to obtain TISAX certification, a cybersecurity assessment framework for the automotive sector. With these certifications, the company has expanded its safety verification scope to include industrial robots and smart factories, in addition to automotive applications.
Building on these achievements, SK hynix plans to expand its partnerships with global Tier 1 automotive suppliers and autonomous driving platform clients, while also seeking opportunities to supply LPDDR products in the edge AI and industrial robot markets.
Kim Jong-hwan, Vice President of DRAM Development at SK hynix, stated, "It is becoming increasingly important to internalize safety and security systems that comply with international standards in the memory development process. We will strengthen our competitiveness in the physical AI market based on our proven technological capabilities."
