Micron Technology announced that it has begun sampling the industry’s first automotive low-power DDR5 DRAM (LPDDR5) memory that is hardware-evaluated to meet the most stringent Automotive Safety Integrity Level (ASIL), ASIL D. The solution is part of Micron’s new portfolio of memory and storage products targeted for automotive functional safety based on the International Organization for Standardization (ISO) 26262 standard.
Micron’s functional safety-evaluated DRAM is compatible with advanced-driver assistance system (ADAS) technologies, including adaptive cruise control, automatic emergency braking systems, lane departure warning and blind spot detection systems. Micron’s LPDDR5’s high performance, superior power efficiency and low latency provide the requisite performance and headroom to keep pace with increasing bandwidth requirements of next-generation automotive systems.
“Autonomous vehicles promise to make our roads safer, but they need powerful, trusted memory that can enable real-time decision-making in extreme environments,” said Kris Baxter, corporate vice president and general manager of Micron’s Embedded Business Unit. “To fulfill this growing market need, we’ve optimized our automotive LPDDR5 to deliver the utmost performance, quality and reliability for the smart, safe cars of tomorrow.”
As electronic components in cars become integral for safety, automakers must meet strict functional safety standards that require mechanisms to mitigate risk in the event of malfunctions. Recognizing the growing importance of functional safety, Micron has established an office dedicated to collaborating with customers on the memory requirements of designing safe automotive systems. To help customers navigate complex compliance obligations, this office has spearheaded the launch of LPDDR5 with a safety application note and the industry’s first supplier-provided hardware evaluation report of DRAM. Micron’s hardware evaluation has also been independently assessed and verified by exida, a renowned expert in automotive safety. By taking on this demanding evaluation in-house, Micron simplifies system design and speeds time to market for automotive customers.
