A method and apparatus to efficiently transmit data. The method and apparatus effectively aggregate data and transmit the data in a high-speed power line communication (PLC) network. The method of transmitting the data includes combining each of at least one or more data units transferred from an upper layer, with a field to indicate attribute information of the data unit, dividing the combined data units and fields into frame blocks of an identical size, and aggregating the divided frame blocks and transferring the aggregated frame blocks as one frame to a PHY layer. In this way, data units of a variety of types and sizes transferred from the upper layer are aggregated and transmitted as the one frame.

A method of distributing group identifiers IDs (GIDs) in a power line communication (PLC) network, a method of receiving the GIDs, an authentication apparatus, and a PLC apparatus are provided. The authentication apparatus includes: an authentication mode storing unit which stores an authentication mode having a value including one of an authentication authorized mode and an authentication unauthorized mode; a GID request receiver which receives a GID request message from a PLC apparatus; and a GID transmitter which, if the authentication mode is the authentication authorized mode, transmits a GID corresponding to the PLC apparatus to the PLC apparatus. Authentication is realized in a PLC media access control layer distributing the GIDs between a PLC apparatus and an authentication apparatus, so manually inputting a GID into the PLC apparatus is not necessary. Further, the GIDs are distributed via the authentication apparatus, thereby centrally managing the GIDs.

摘要:
Provided is a vertical non-volatile memory device in which a capacitor constituting a peripheral circuit region is formed as a vertical type so that an area occupied by the capacitor in the entire device can be reduced as compared with a planar capacitor. Thus, a non-volatile memory device may be highly integrated and have a high capacity. The device includes a substrate having a cell region and a peripheral circuit region, a memory cell string including a plurality of vertical memory cells formed in the cell region and channel holes formed to penetrate the vertical memory cells in a first direction vertical to the substrate, an insulating layer formed in the peripheral circuit region on the substrates at substantially the same level as an upper surface of the memory cell string, and a plurality of capacitor electrodes formed on the peripheral circuit region to penetrate at least a portion of the insulating layer in the first direction, the plurality of capacitor electrodes extending parallel to the channel holes. The plurality of capacitor electrodes are spaced apart from one another in a second direction parallel to the substrate, and the insulating layer is interposed between a pair of adjacent capacitor electrodes from among the plurality of capacitor electrodes.
