A semiconductor device includes a mapping table that stores a corresponding relation between a logical address defined on a basis of regions and a physical address defined on a basis of extents, wherein one or more extents are dynamically allocated to one region.

Semiconductor device and operating method thereof

A method for fabricating a nonvolatile memory device includes forming a stacked structure having a plurality of interlayer dielectric layers and a plurality of sacrificial layers wherein interlayer dielectric layers and sacrificial layers are alternately stacked over a substrate, forming a first hole exposing a part of the substrate by selectively etching the stacked structure, forming a first insulation layer in the first hole, forming a second hole exposing the part of the substrate by selectively etching the first insulation layer, and forming a channel layer in the second hole.
