Persistent memory makes cars smarter

Cars are getting smarter. Whether it's navigation aids, entertainment systems or electronic stabilization controls and active safety measures, the embedded processing capability in cars will continue to increase. According to Gartner Dataquest, 30 percent of a new car's cost by 2014 will be electronics, and semiconductor content will account for an increasing share of that cost. Most of these automotive systems are processing information based on current conditions, not on historical information. As illustrated in our imaginary scenario, much more intelligent operation can be accomplished with the inclusion of persistent memory.

Modern vehicles typically have some type of persistent memory, but it is far from being total recall. Persistent memory may include magnetic memory devices such as HDDs, non-volatile solid-state memory or SRAM that remains connected to a power source when the car is off.
