Some of the nanoelectronics areas under development, which you can explore in more detail by following the links provided in the next section, include the following topics.</p> <p>Improving display screens on electronics devices. This involves reducing power consumption while decreasing the weight and thickness of the screens.</p> <p>Increasing the density of memory chips. Researchers are developing a type of memory chip with a projected density of one terabyte of memory per square inch or greater.</p> <p>Reducing the size of transistors used in integrated circuits.
