Concept on world production shortage of microchips and semiconductors.gettyImagine you’re driving down a highway at night, across a desolate stretch—let's say Highway 22E in Alaska, 200 miles from the nearest town, with the temperature outside a shocking -40°F—when the dashboard of your brand-new SUV flickers and dies. No warning, no sign of anything wrong with the car. The issue: faulty DRAM. Confused? Don’t be. You’re probably one of the many people who don’t know what DRAM is. Modern cars run on dozens of computers, but what is more obscure is that those computers rely on DRAM: dynamic random-access memory, a fast, volatile memory that holds active data while a processor works, which, it turns out, is as essential to your vehicle's electronics as fuel is to its engine. DRAM is probably something only the most avid car enthusiasts have heard of, yet a global shortage of it is quietly becoming one of the auto industry's most disruptive—and underreported—crises.Today’s vehicles are becoming increasingly smart, and the DRAM chip powering the vehicle's computer is at the heart of it all. DRAM (Dynamic Random-Access Memory) is a type of memory chip that temporarily stores data as it is processed—like a place to keep and use information in real time, rather than a place to store it long-term. Modern smart cars can have up to 150 microprocessors that control everything, right from infotainment and advanced driver assistance systems to ECUs and vehicle telematics. And as they grow smarter—think software-defined vehicl...
