Abstract:
1. A semiconductor integrated circuit comprising: a data transmitting circuit that transmits transmission data through a plurality of signal lines and a strobe signal in synchronization with the transmission data, wherein the data transmitting circuit comprises: a plurality of data output circuits that output the transmission data and set an output of the data output circuit to a high impedance state, each of the plurality of data output circuits being provided for a corresponding one of the plurality of signal lines; a plurality of data selection circuits, each of which selects one of the transmission data and preliminary-set fixed data, and outputs the selected data to a corresponding one of the data output circuits; and a control circuit that controls the data output circuits and the data selection circuits so that each of the data output circuits outputs the fixed data during a period between when the high impedance state of the output of the data output circuits terminates and when the data output circuits start to output the transmission data.
