Abstract: A resistive sense memory cell includes a layer of crystalline praseodymium calcium manganese oxide and a layer of amorphous praseodymium calcium manganese oxide disposed on the layer of crystalline praseodymium calcium manganese oxide forming a resistive sense memory stack. A first and second electrode are separated by the resistive sense memory stack. The resistive sense memory cell can further include an oxygen diffusion barrier layer separating the layer of crystalline praseodymium calcium manganese oxide from the layer of amorphous praseodymium calcium manganese oxide a layer. Methods include depositing an amorphous praseodymium calcium manganese oxide disposed on the layer of crystalline praseodymium calcium manganese oxide forming a resistive sense memory stack.
