Over the past few years, there has been an increasing demand for NOR Flash memory for use in automotive applications. Initial uses included applications such as infotainment and engine control. However, as advancements in automotive computerization continue to progress, NOR Flash memory is seeing use in a wider range of various automotive applications. In particular, there has been rapid growth in demand for NOR Flash memory for use in Advanced driver-assistance systems (ADAS), digital instruments clusters, and infotainment systems.

ADAS has seen rapid market growth. Currently, many ADAS applications utilize cameras – typically back up cameras – to assist drivers in identifying nearby hazards (Figure 1). Sensing cameras are even more sophisticated, providing drivers with automated collision avoidance, lane changing, parking, and more. The sensing camera market is expected to continue to expand as cars become increasingly autonomous. Given that sensing cameras need even more complex processing than viewing cameras, highly-efficient SoCs will be required to support this advanced technology (Figure 2). Demand for NOR Flash memory that is both high density and high performance will continue to grow in conjunction with this increase in program size.
