    Mobile Applications

    Consumers have come to expect the entertainment experience of the living room from the mobile devices they carry every day. Advanced mobile devices offer high-definition (HD) resolution video recording, multi-megapixel digital image capture, 3D gaming and media-rich web applications. To pack all that functionality in a form factor that's thin, light and delivered with a pleasing aesthetic presents a tremendous challenge for mobile device designers. Chief among these challenges is the implementation of a high-performance memory architecture that meets the power efficiency constraints of battery-operated products.

    In order to support these advanced mobile devices, memory bandwidth will experience significant growth. Over the course of the next 2-3 years, mobile gaming and graphics applications will push memory bandwidth requirements to 12.8 gigabytes per second and beyond. This bandwidth must be achieved within the constraints of the available battery life and cost budget.

    Learn more about how Rambus innovations and solutions can address the high-performance and low-power requirements of advanced mobile devices.
