EETimes publishes an article based on a talk to Rambus' Chief Marketing Officer Jerome Nadel. Discussing the company new direction to concentrate on technology, rather than on patents, EETimes mentions:
"The promising technologies being worked at Rambus include binary pixel technology. This uses high-frequency binary sampling of light on an image sensor array combined with local image processing to improve low-light sensitivity for video and photos.
Also in the works is a lensless image sensor that uses application-specific phase gratings and local data processing to extract relevant information in Internet-of-Things applications."
