Abstract
A semiconductor device includes a first substrate structure and a second substrate structure. The first substrate structure includes a base substrate, circuit elements disposed on the base substrate, a first substrate disposed on the circuit elements, first memory cells disposed on the first substrate and electrically connected to the circuit elements, first bit lines disposed on the first memory cells and connected to the first memory cells, and first bonding pads disposed on the first bit lines to be connected to the first bit lines, respectively. The second substrate structure is connected to the first substrate structure on the first substrate structure, and includes a second substrate, second memory cells disposed on the second substrate, second bit lines disposed on the second memory cells and connected to the second memory cells, and second bonding pads disposed on the second bit lines to be connected to the second bit lines, respectively. The first substrate structure and the second substrate structure are connected to each other by bonding the first bonding pads to the second bonding pads, and the first bonding pads and second bonding pads are vertically between the first bit lines and the second bit lines, without the first substrate or second substrate disposed vertically between the first bit lines and the second bit lines.
