Abstract

Nonvolatile memory devices are provided. Devices include active regions that may be defined by device isolation layers formed on a semiconductor substrate and extend in a first direction. Devices may also include word lines that may cross over the active regions and extend in a second direction intersecting the first direction. The active regions have a first pitch and the word lines have a second pitch that is greater than the first pitch.
