Micron Technology, Inc. said it has started sampling the industry’s first automotive low-power DDR5 DRAM (LPDDR5) memory.

It said the memory is hardware-evaluated to meet the most stringent Automotive Safety Integrity Level (ASIL), ASIL D.

The solution is part of Micron’s latest portfolio of storage and memory products targeted for automotive functional safety based on the International Organization for Standardization (ISO) 26262 standard.

The company’s functional safety-evaluated DRAM is compatible with advanced-driver assistance system (ADAS) technologies, such as automatic emergency braking systems, adaptive cruise control, lane departure warning and blind spot detection systems .

Micron said LPDDR5’s superior power efficiency, high performance and low latency offer the requisite performance and headroom to keep pace with increasing bandwidth requirements of next-generation automotive systems.

Kris Baxter, corporate vice president and general manager of Micron’s Embedded Business Unit, said, “Autonomous vehicles promise to make our roads safer, but they need powerful, trusted memory that can enable real-time decision-making in extreme environments.”

He added:“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.”

Cars’ safety

With electronic components in cars becoming integral for safety, automakers must meet strict functional safety standards that require mechanisms to reduce risk in the event of malfunctions.

Understanding the growing importance of functional safety, Micron has established an office exclusively for collaborating with customers on the memory requirements of designing safe automotive systems.

In a bid 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.
