Automotive Memory – A higher standard

Automotive Memory – A higher standard

In our last blog Semiconductors in Automotive, we discussed the different types of memory being used in the various systems of automobiles and how the need for memory is increasing. For today's automotive memory solutions, high temperature and quality standards are key. Connected car applications require specific memory solutions due to the stringent quality, reliability, and operating temperature requirements of the automotive market. The critical nature of these systems leaves minimal margin for error.

Not only are performance and more advanced systems driving this, but the relative location of the memory pushes the boundaries. Think of the forward looking camera right behind the windshield with no airflow and the sun beating down on it during a hot Texas summer. Combine that with the proximity to the processor and the volatile memory quickly heats above the 105ºC range quickly pushing towards 125ºC and the nonvolatile sees a similar increase from 85ºC to 105ºC. The automotive market's unique set of feature requirements include:

  • Zero Defect Approach – Targeting no failures over the product lifecycle
  • Continuous Improvement Process – Persistent focus on improving the overall quality of products, including legacy products
  • Automotive-Grade Selection – Strict selection criteria in fabrication, assembly, and test to ensure the highest quality product
  • Long Lifecycle – 10- to 15-year product availability and support
  • Burn-In Flow – Simulating the first year of product life to improve overall quality, which is statistically when marginal products fail
  • Automotive Certification of Fab and Assembly Sites – Fab and assembly certification to ISO/TS 16949
  • AEC-Q100 – A failure mechanism-based stress test qualification for integrated circuits]
  • Automotive documentation such as:
    • Production part approval process (PPAP) documentation – Additional documentation stating where die is fabricated, parts are assembled, and testing is conducted so there is a formal return merchandise authorization (RMA) trail
    • 8D failure mode and effects analysis (FMEA) support – In-depth support with guaranteed timelines and clear steps for improvement

Micron is focused on the automotive market segment with parts purposed built to meet the above standards. We continue to work closely with manufacturers and their suppliers to define the next generation memory. We’ve become a leading provider of automotive memory solutions – not by chance, but by design.

    Hi james, do you have any roadmap for HMC components for Automotive ?

  • Web Support on November 28, 2016

    Yoni, Besides HMC, Micron has a variety of products on the roadmap to meet the needs of the automotive market segment. We are also working closely with market leaders to define the next generation of memory solutions to meet the growing demands. Can we contact you directly to discuss?

    i will be happy if you do that by mail- YONI.HERBSMAN@ELBITSYSTEMS.COM we are looking for a serial memory like the HMC but with industrial use
