Micron Technology has introduced 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.
“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.”
“Functional safety is essential to the development of advanced automotive systems, but to date, memory has had a somewhat neglected commercial off-the-shelf existence,” said Alexander Griessing, chief operating officer and principal safety expert at exida. “Micron has launched its industry-leading automotive LPDDR5 with a laser focus on ISO 26262, setting a new standard for the rest of the memory industry. This increased attention to functional safety will benefit all, from automakers to consumers who need advanced, safe vehicles.”
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 the increasing bandwidth requirements of next-generation automotive systems.
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.
Micron’s automotive LPDDR5 is also ruggedized to support extreme temperature ranges and qualified for automotive reliability standards such as Automotive Electronics Council-Q100 and International Automotive Task Force 16949.
Accompanied by extensive functional safety collateral, Micron’s LPDDR5 supports customers in conducting comprehensive safety analysis during system configuration.
Micron’s deep expertise stems from a tight collaboration with automotive customers on designing memory into the system architecture that underpins ADAS, in-vehicle infotainment, digital cockpits and machine learning.
As the market share leader, Micron is uniquely positioned as the top memory supplier to the automotive market.
