Classification: CPC G  H | IPC G  H

Claim 0:
1. A three-dimensional (3D) memory device, comprising:
a first semiconductor structure comprising an array of memory cells, a first peripheral circuit of the array of memory cells, and a polysilicon layer between the array of memory cells and the first peripheral circuit, the first peripheral circuit comprising a first transistor, and a source contact being arranged on an opposite side of the polysilicon layer with respect to a channel structure of the array of memory cells; and
a second semiconductor structure comprising a second peripheral circuit of the array of memory cells, the second peripheral circuit comprising a second transistor,
wherein:
the first semiconductor structure is connected with the second semiconductor structure;
the polysilicon layer is in contact with the array of memory cells at one side of the polysilicon layer and in direct contact with an interconnect layer corresponding to the first peripheral circuit at another side of the polysilicon layer; and
a conductive material extends through the polysilicon layer to couple the array of memory cells with the first peripheral circuit through the interconnect layer.
