Abstract
A three-dimensional semiconductor memory device, including a peripheral circuit structure including a first metal pad and a cell array structure disposed on the peripheral circuit structure and including a second metal pad. The peripheral circuit structure may include a first substrate including a first peripheral circuit region and a second peripheral circuit region, first contact plugs, second contact plugs, and a first passive device on and electrically connected to the second contact plugs. The cell array structure may include a second substrate disposed on the peripheral circuit structure, the second substrate including a cell array region and a contact region. The cell array structure may further include gate electrodes and cell contact plugs. The first passive device is vertically between the gate electrodes and the second contact plugs and includes a first contact line. The first metal pad and the second metal pad may be connected by bonding manner.
