Micron Technology has begun sampling its automotive low-power DDR5 DRAM (LPDDR5) memory that is hardware-evaluated to meet the most stringent Automotive Safety Integrity Level (ASIL) D, according to the company.
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 said its LPDDR5’s high performance, 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 VP and GM of Micron’s embedded BU. “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.
“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, COO 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.”
