    摘要: The nonvolatile memory device includes a semiconductor substrate, and a device isolation layer defining an active region in the semiconductor substrate. The device isolation layer includes a top surface lower than a top surface of the semiconductor substrate, such that a side-upper surface of the active region is exposed. A sense line crosses both the active region and the device isolation layer, and a word line, spaced apart from the sense line, crosses both the active region and the device isolation layer.

    摘要: A non-volatile memory device includes a memory cell block, a first switching block, and a second switching block. A plurality of memory cells are arranged in the memory cell block and each of the memory cells includes a memory transistor having a floating gate and a control gate and is connected to a local bit line and includes a selection transistor connected to the memory transistor in series that is connected to a source line. The first switching block selectively connects a global bit line to the local bit line and the second switching block controls the memory cells in the memory cell block in units of a predetermined number of bits. The first switching block includes at least two switching devices connected in parallel between the global bit line and the local bit line.

    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 nonvolatile memory device includes first and second impurity diffusion regions formed in a semiconductor substrate, and a memory cell formed on a channel region of a semiconductor substrate between the first and second impurity diffusion regions. The memory cell includes a stacked gate structure formed on the channel region, and first and second select gates formed on the channel regions and opposite sidewalls of the stacked gate structure. Since the first and second select gates are spacer-shaped to be self-aligned on opposite sidewalls of the stacked gate structure, a size of a memory cell is reduced to enhance an integration density of a semiconductor device.
