Abstract

This invention belongs to the technical field of memories and specifically relates to a resistive random access memory structure with an electric-field strengthened layer and a manufacturing method thereof. The resistive random access memory in the present invention can include a top electrode, a bottom electrode and a composite layer which is placed between the top electrode and the bottom electrode and have a first resistive switching layer and a second resistive switching and electric-field strengthened layer; the second resistive switching and electric-field strengthened layer cab be adjacent to the first resistive switching layer and have a dielectric constant lower than that of the first resistive switching layer. The electric-field distribution in the RRAM unit is adjustable.
