Claim Text:
1. A phase change memory cell, comprising: a first carbon nanotube layer; a phase change layer, wherein at least part of the phase change layer is overlapped with the first carbon nanotube layer; a first electrode and a second electrode electrically connected with the first carbon nanotube layer, wherein the first electrode and the second electrode are configured to apply a first voltage to the first carbon nanotube layer; and a third electrode electrically connected with the phase change layer, wherein the third electrode and the first electrode are configured to apply a second voltage to the phase change layer; a first projection of the third electrode and a second projection of the first electrode intersect with each other to define a intersection, and the carbon nanotube layer and the phase change layer are sandwiched between the first electrode and the second electrode at the intersection.
