High-performance computers based on AI use deep neural network algorithms that allow autonomous cars to drive better than human-driven cars. A host of sensors work together to see the entire environment in 360 degrees, 24/7, at a greater distance and with a higher accuracy than humans can.
Imagine a car slamming on its brakes on a busy freeway. Through vehicle-to- vehicle and vehicle-to-infrastructure (collectively called V2X) communication, this event could be transmitted to oncoming cars, allowing themto avoid an accident.
SAFETY IN DETAIL The attention to redundancies de

systems to avoid bad decisions; it also includes infrastructure that allows self- driving cars to communicate with each other and their surrounding environment. This wireless interconnection, along with hardware redundancies, is governed by legislation that mandates safety requirements for differing levels of autonomy.
The NHSTA has established levels ranging fromLevel 0, meaning no automation, to Level 5, or full automation. The maj self-driving cars

historically drove memory technology, the automotive industry is likely to drive future memory technologies. For example, a vendor recently introduced an artificial intelligence platformfor autonomous driving, which is based on the industry’s leading-edge DRAM technologies. This platformdelivers more than 1TB per second of memory bandwidth to achieve Level 5 performance.
Micron has led the industry in both automotive memory solutions and graphics memories such as GGDR5 and GDDR6. The bandwidth associated with GDDR6 memories fa levels of autonomy i

An autonomous compute platform that’s rich in memory bandwidth can evolve and refine self-driving algorithms. Over time, we will see improvements in algorithms. But those will be deployed as software upgrades, similar to how your smart phone receives regular updates.

based on computer hardware using relative mature and low-bandwidth memory devices. As driverless cars become more autonomous,memory technologies move fromthe back seat to the front to improve safety and performance.
The highest-performance memory technology available today, GDDR6 can operate in the high heat and harsh conditions associated with the automobile. In addition, GDDR6 is capable of fuelling AI compute engines that enable self-driving cars to address National Highway Safety Transport Association (NHSTA) and Society of Automotive Engineers (SAE) safety standards.
