Abstract
Embodiments of three-dimensional (3D) memory devices and methods for forming the 3D memory devices are disclosed. In an example, a NAND memory device includes a substrate, one or more peripheral devices on the substrate, a plurality of NAND strings above the peripheral devices, a single crystalline silicon layer above and in contact with the NAND strings, and interconnect layers formed between the peripheral devices and the NAND strings. In some embodiments, the NAND memory device includes a bonding interface at which an array interconnect layer contacts a peripheral interconnect layer.
