Patent ID: 8102186

Claim:
A semiconductor integrated circuit comprising: first and second transmitter-receivers that execute transmission and reception of data through a signal line, wherein the first transmitter-receiver comprises: a first termination circuit that includes a first resistor and a first switch, the first resistor being provided between a first power supply terminal and the signal line, the first switch controlling a current flowing through the first resistor to be turned on and off; and a control circuit that outputs a first control signal to the first termination circuit so that the first switch is turned on when the first transmitter-receiver receives data, the first switch is turned off when the first transmitter-receiver transmits the data, and the first switch is continuously on during a first predetermined period after receiving the data when the first transmitter-receiver further receives another data after receiving the data, wherein the first predetermined period is decided based on a data reception interval of the first transmitter-receiver, wherein the control circuit outputs the first control signal so that the first switch is turned off instead of being continuously on when the first transmitter-receiver continuously further receives another data after receiving the data and when the data reception interval exceeds a predetermined threshold.
