More Information
Summary:Provided are a nonvolatile memory device and a method of manufacturing the same. The device includes a semiconductor substrate; a source region and a drain region disposed in the semiconductor substrate and a channel region interposed between the source and drain regions; a first tunnel oxide layer disposed on the channel region near the source region; a second tunnel oxide layer disposed on the channel region near the drain region; a first charge trapping layer disposed on the first tunnel oxide layer; a second charge trapping layer disposed on the second tunnel oxide layer; a blocking oxide layer covering the first and second charge trapping layers; a charge isolation layer interposed between the first and second charge trapping layers; and a gate electrode disposed on the blocking oxide layer.
