Abstract: A semiconductor memory device includes a first sense amplifier which senses data on a first line pair and generates a first output signal; and a test unit which senses the data on a first line pair and transfers a second output signal to a second line in response to a test mode signal.

Abstract: A mobile terminal and an operating method of the mobile terminal are provided. The mobile terminal may be coupled, either wirelessly or by wire, to an external terminal and the mobile terminal may thus receive sync data including information regarding a webpage currently being displayed by the external terminal from the external terminal or a server. The mobile terminal may display the same webpage as is currently being displayed by the external terminal based on the received sync data.

Abstract: An auto-precharge signal generation circuit comprises a signal generator, a set signal generator, and an auto-precharge signal generator. The signal generator is configured to generating a control signal and a precharge control signal in response to receiving a first column address strobe signal and an auto-precharge flag signal. The set signal generator is configured to generating a set signal in response to receiving the control signal and the precharge control signal. The auto-precharge signal generator is configured to generate an auto-precharge signal in response to receiving the set signal and a period set signal.

Abstract: In a tunneling method and apparatus for multicasting between an IPv4 network and an IPv6 network, a multicast table containing information about receive and transmit interfaces in a multicast delivery tree structure for each of the IPv4 network and the IPv6 network is set, a multicast address area is assigned to the first network and a multicast address area is assigned to the second network compatible with the first network, an IPv6 multicast packet containing source and multicast destination addresses of the IPv6 network is received, and when a destination network of the IPv6 multicast packet is the IPv6 network connected to the IPv4 network, source and multicast destination addresses of the IPv4 network are extracted from source and multicast destination addresses contained in the IPv6 multicast packet, the IPv6 multicast packet is capsulated into an IPv4 format, and the IPv4 format packet is multicast-tunneled to the IPv6 network through the IPv4 network by referring to the multicast table.
