Abstract:
1. A method for programming a carbon nanotube memory cell, wherein the memory cell comprises a first conductor, a steering element, a carbon nanotube fabric, and a second conductor, wherein the steering element and the carbon nanotube fabric are arranged electrically in series between the first conductor and the second conductor, and wherein the entire carbon nanotube memory cell is formed above a substrate, the carbon nanotube fabric having a first resistivity, the method comprising: applying a first electrical set pulse between the first conductor and the second conductor, wherein, after application of the first electrical set pulse, the carbon nanotube fabric has a second resistivity, the second resistivity less than the first resistivity; and after applying the first electrical set pulse, applying a first electrical reset pulse across the steering element and the carbon nanotube fabric, wherein, after application of the first electrical reset pulse, the carbon nanotube fabric has a third resistivity, the third resistivity greater than the second resistivity.
