SEOUL, January 19 (AJP) - SK hynix said Monday it has obtained the highest functional safety certification for its LPDDR5X automotive memory, as demand grows for reliable semiconductors used in advanced driver-assistance and autonomous-driving systems.
The South Korean chipmaker said its LPDDR5X DRAM has been certified at ASIL-D, the highest safety level under the ISO 26262 international automotive functional safety standard.
ASIL-D applies to systems directly linked to passenger safety, including autonomous-driving control and advanced driver-assistance systems (ADAS). Certification was conducted by global safety testing body TÜV SÜD, which assessed the company’s development, design, verification and quality-management processes.
SK hynix said the certified memory is designed for use in ADAS, autonomous driving and in-vehicle infotainment systems, where stable processing of large volumes of data is required.
As vehicles increasingly rely on software-based architectures, known as software-defined vehicles (SDVs), functional safety has become a key requirement for automotive semiconductors, alongside performance and power efficiency.
Under ISO 26262, automotive components are evaluated based on severity, exposure and controllability of potential failures, with ASIL-D representing the strictest criteria.
SK hynix said its LPDDR5X automotive memory incorporates safety mechanisms including error detection and correction, fault-diagnosis functions and redundancy designs to reduce the risk of random hardware failures.
The company said the certification supports its strategy to expand its presence in the automotive memory market, where safety validation is becoming a prerequisite for supplier selection by global automakers.
SK hynix did not disclose shipment volumes or customer details.
