Claim 13:
14. A three-dimensional semiconductor device, comprising:
a microprocessor chip, comprising:
at least one microprocessor device; and
a first interconnect layer disposed on the at least one microprocessor device, the first interconnect layer comprising at least one first interconnect structure;

a first memory chip, comprising:
at least one first memory cell; and
a second interconnect layer disposed on the at least one first memory cell, the second interconnect layer comprising at least one second interconnect structure; and

a second memory chip, comprising:
at least one second memory cell; and
a third interconnect layer disposed on the at least one second memory cell, the third interconnect layer comprising at least one third interconnect structure,

wherein the first interconnect layer of the microprocessor chip is bonded with the first memory chip, and the at least one microprocessor device of the microprocessor chip is electrically connected with the at least one first memory cell of the first memory chip through the at least one first interconnect structure or the at least one second interconnect structure; and
wherein the third interconnect layer of the second memory chip is bonded with the second interconnect layer of the first memory chip, and the at least one microprocessor device of the microprocessor chip is electrically connected with the at least one second memory cell of the second memory chip through the at least one first interconnect structure, the at least second interconnect structure, or the at least one third interconnect structure.
