Abstract
A resistive random access memory (RRAM) structure includes a RRAM cell, spacers and a dielectric layer. The RRAM cell is disposed on a substrate. The spacers are disposed beside the RRAM cell, wherein widths of top surfaces of the spacers are larger than or equal to widths of bottom surfaces of the spacers. The dielectric layer blanketly covers the substrate and sandwiches the RRAM cell, wherein the spacers are located in the dielectric layer. A method for forming the resistive random access memory (RRAM) structure is also provided.
