Abstract:
1. A phase change memory cell, comprising: a first row electrode lead and a second row electrode lead spaced from each other; a first column electrode lead and a second column electrode lead spaced from each other, wherein the first column electrode lead is intersected with and spaced from the first row electrode lead and the second row electrode lead, and the second column electrode lead is intersected with and spaced from the second row electrode lead to define an intersection; a carbon nanotube layer and a phase change layer stacked together and sandwiched between the second row electrode lead and the second column electrode lead at the intersection; a first electrode electrically connected to the first row electrode lead; a second electrode electrically connected to the first column electrode lead, wherein the second electrode is spaced from the first electrode, and the carbon nanotube layer is electrically connected to the first electrode and the second electrode.
