Abstract:
1. A nonvolatile memory device comprising: an active region defined by a device isolation layer in a substrate; a word line crossing the active region; a nonvolatile memory cell charge storage region defined by a crossing of the active region and the word line and disposed between the active region and the word line, wherein the nonvolatile memory cell charge storage region is disposed at an oblique angle with respect to the word line, wherein the active region extends in a first direction and the word line extends in a second direction orthogonal to the first direction, wherein at least part of the active region has a zigzag configuration that includes a corner which is positioned adjacent a side surface of the word line; and string selection lines and ground selection lines extending in the second direction, wherein the active region disposed between the string selection line and the ground selection line has a zigzag configuration, and wherein the active region disposed between the string selection lines and between the ground selection lines has a straight line configuration.
