IBM showed off several novelties, including a graphene-based chip, world's first transistor with sub-10nm channel lengths and also Racetrack memory. Full details about these technologies can be read at X-bit Labs.
IBM researchers also demonstrated the first transistor with sub-10 nm channel lengths, outperforming the best competing silicon-based devices at these length scales.
While already being considered in varied applications ranging from solar cells to displays, it is expected that computers with in the next decade will use transistors with a channel length below 10 nm, a length scale at which conventional silicon technology will have extreme difficulty performing even with new advanced device architectures. The scaled carbon nanotube devices below 10nm gate length are a significant breakthrough for future applications in computing technology.
