Abstract
A semiconductor memory device includes a first channel structure which is adjacent to an insulating structure and penetrates a plurality of conductive layers, a second channel structure which is spaced apart from the insulating structure and penetrates the plurality of conductive layers, a first impurity region included in an end portion of the first channel structure, and a second impurity region included in an end portion of the second channel structure. A doping concentration of an impurity in the first impurity region is different from a doping concentration of an impurity in the second impurity region.
