    摘要: A method of refreshing a semiconductor memory device includes performing a first refresh operation for memory cells included in a memory cell array, and determining whether a command other than a refresh command is applied to the semiconductor memory device in a refresh cycle of the first refresh operation. The method further includes continuing to perform the first refresh operation when a command other the refresh command is applied to the semiconductor memory device in one refresh cycle of the first refresh operation, and performing a second refresh operation when a command other than the refresh command is not applied to the semiconductor memory device in one refresh cycle of the first refresh operation. A refresh time of the second refresh operation is greater than a refresh time of the first refresh operation.

    摘要: In a communication system, data is selectively transmitted using single-ended or differential signaling. The data is transmitted in relation to a plurality of clock signals having different relative phases. When the data is transmitted using single-ended signaling, data on adjacent signal lines undergo logic transitions at different times in relation to the plurality of clock signals.

    摘要: A semiconductor device is provided. The semiconductor device applies data applied through a bump pad on which a bump is mounted through a test pad to a test apparatus such that the reliability of the test can be improved. The amount of test pads is significantly reduced by allowing data output through bump pads to be selectively applied to a test pad. Data and signals applied from test pads are synchronized with each other and applied to bump pads during a test operation such that the reliability of the test can be improved without the need of an additional test chip.
