Abstract:
A semiconductor memory device includes: a substrate including a cell region and a connection region; a first word line stack comprising a plurality of first word lines that extend to the connection region and are stacked on the cell region,; a second word line stack comprising a plurality of second word lines that extend to the connection region and are stacked on the cell region, the second word line being adjacent to the first word line stack; vertical channels in the cell region of the substrate, the vertical channels being connected to the substrate and coupled with the plurality of first and second word lines; a bridge region that connects the first word lines of the first word line stack with the second word lines of the second word line stack; and a local planarized region under the bridge region.
Abstract:
An electronic apparatus connected to a server providing real-time messaging through a messaging channel to communicate therewith is provided. The apparatus includes a client communication unit for communicating with the server and at least one external device, the electronic apparatus and the at least one external device forming a client group, and a client controller for classifying the electronic apparatus and the at least one external device in the client group into a header client connected with the messaging channel to the server and a node client, and for controlling the header client to transmit a message about the node client from the server to the node client when the message from the server is transmitted to the header client through the messaging channel.

Abstract:
User devices, a communication server and a control method are provided. The control method of the user devices includes registering the user devices to a communication server that provides a service of a virtual device network, receiving a virtual Internet Protocol (IP) address of a counterpart device included in the virtual device network from the communication server, determining whether an application attempts to perform data communication with the counterpart device using the virtual IP address, and performing the data communication with the counterpart device according to information provided from the communication server if the application attempts to perform data communication with the counterpart device using the virtual IP address.
