Abstract

Three-dimensional (3D) memory devices are provided. An exemplary 3D memory device includes a first semiconductor structure including a peripheral circuit, a data processing circuit, and a first bonding layer including a plurality of first bonding contacts. The peripheral circuit and the data processing circuit are stacked over one another vertically on different planes. The 3D memory device also includes a second semiconductor structure including an array of 3D NAND memory strings and a second bonding layer including a plurality of second bonding contacts. In addition, the 3D memory device includes a bonding interface between the first bonding layer and the second bonding layer. The first bonding contacts are in contact with the second bonding contacts at the bonding interface.
