Abstract: An integrated circuit device includes: a substrate having a cell region, a peripheral circuit region, and an interconnection region between the cell region and the peripheral circuit region; a first cell stack structure and a second cell stack structure on the first cell stack structure, each including a plurality of insulating layers and a plurality of word line structures alternately stacked on the substrate; and a dummy stack structure located at a same vertical level as the second cell stack structure, and including a plurality of dummy insulating layers and a plurality of dummy support layers alternately stacked in the peripheral circuit region.

Abstract: A content reproduction apparatus includes an outputter configured to output audio and video, a user interface configured to receive an utterance input from a user, a memory storing one or more instructions, and a processor configured to execute the one or more instructions stored in the memory. The processor is configured to control the outputter to output a first screen in which one or more objects selectable by the user's utterance are included and a focus is displayed with respect to one of the one or more objects, and, to control the outputter to output utterable guide information for a next selection according to the object corresponding to the focus displayed, when the user does not provide an utterance through the user interface.

Abstract: An image forming apparatus transmits a fax document using a cloud server which stores fax communication history information with respect to fax numbers. The image forming apparatus includes an image forming job performer to perform a fax function, a communicator to communicate with the cloud server, and a controller to request the cloud server for fax transmission setting information corresponding to a fax number of another image forming apparatus, receive a request result from the cloud server in response to the request, and transmit a fax document to the another image forming apparatus by applying, to the image forming job performer, a fax transmission setting based on the received request result.
