摘要： A non-volatile memory device includes a floating gate formed on a substrate with a gate insulation layer interposed therebetween, a tunnel insulation layer formed on the floating gate, a select gate electrode inducing charge introduction through the gate insulation layer, and a control gate electrode inducing charge tunneling occurring through the tunnel insulation layer. The select gate electrode is insulated from the control gate electrode. According to the non-volatile memory device, a select gate electrode and a control gate electrode are formed on a floating gate, and thus a voltage is applied to the respective gate electrodes to write and erase data.

摘要： In a split gate type nonvolatile memory device and a method of fabricating the same. A supplementary layer pattern is disposed on a source region of a semiconductor substrate. Since the source region is vertically extended by virtue of the presence of the supplementary layer pattern, it is therefore possible to increase an area of a region where a floating gate overlaps the source region and the supplementary layer pattern. Accordingly, the capacitance of a capacitor formed between the source and the floating gate increases so that it is possible for the nonvolatile memory device to perform program/erase operations at a low voltage level.

摘要： A method of forming a split-gate non-volatile memory cell can include forming first and second adjacent floating gates self-aligned to a field oxide region therebetween. An oxide layer is formed covering the first and second adjacent floating gates and the field oxide region, the oxide layer electrically isolates the first and second adjacent floating gates from one another. A control gate is formed on the oxide layer on the first and second adjacent floating gates. Related devices are also disclosed.
