RESISTIVE RANDOM-ACCESS MEMORY CELL AND MANUFACTURING METHOD THEREOF

An resistive random-access memory (RRAM) device including an first crystalline semiconductor layer disposed adjacent to a crystalline semiconductor substrate, a crystal lattice edge-dislocation segment disposed at an interface of the first crystalline semiconductor layer and crystalline semiconductor substrate, the lattice edge-dislocation segment including first and second segment ends, a first ion-source electrode disposed upon the electrically isolating spacer, adjacent to the crystalline substrate and first crystalline semiconductor layer, and further disposed in contact with the first segment end of the lattice edge-dislocation segment, and a second electrode disposed upon the electrically isolating spacer, adjacent to the crystalline substrate and first crystalline semiconductor layer, and further disposed in contact with the second segment end of the lattice edge-dislocation segment.
