    摘要: A nonvolatile memory device includes a semiconductor substrate, a device isolation film, a tunnel insulation film, a plurality of floating gates, an inter-gate dielectric film, and a control gate pattern. Trenches are formed in the substrate that define active regions therebetween. The device isolation film is in the trenches in the substrate. The tunnel insulation film is on the active regions of the substrate. The plurality of floating gates are each on the tunnel insulation film over the active regions of the substrate. The inter-gate dielectric film extends across the floating gates and the device isolation film. The control gate pattern is on the inter-gate dielectric film and extends across the floating gates. A central region of the device isolation film in the trenches has an upper major surface that is recessed below an upper major surface of a surrounding region of the device isolation film in the trenches. An edge of the recessed central region of the device isolation film is aligned with a sidewall of an adjacent one of the floating gates.

    摘要: Provided is a method for automatically setting an area code by a femto access point (AP) located in a coverage area of a macro cell. The method includes receiving a broadcast signal of the macro cell, extracting an area code of the macro cell from the received broadcast signal, and setting the extracted area code as an area code of the femto cell. The femto AP sets the same area code as that of the macro cell as its area code and transmits the area code of the femto AP to the mobile station, thereby preventing the mobile station from repeating the location registration and enabling the mobile station to receive the same paging message from the femto AP and the macro cell.

    摘要: A nonvolatile memory device may include a substrate having a cell region, and a cell device isolation layer on the cell region of the substrate to define a cell active region. A floating gate may include a lower floating gate and an upper floating gate sequentially stacked on the cell active region, and a tunnel insulation pattern may be between the floating gate and the cell active region. A control gate electrode may be on the floating gate, and a blocking insulation pattern may be between the control gate electrode and the floating gate. More particularly, the upper floating gate may include a flat portion on the lower floating gate and a pair of wall portions extending upward from both edges of the flat portion adjacent to the cell device isolation layer. Moreover, a width of an upper portion of a space surrounded by the flat portion and the pair of wall portions may be larger than a width of a lower portion of the space. Related methods are also discussed.
