半导体集成电路

Abstract

Provided is a semiconductor integrated circuit according to an exemplary aspect of the present invention including first and second transmitter-receivers that execute transmission and reception of data through a signal line. The first transmitter-receiver includes 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.
提供了一种根据本发明的示例性方面的半导体集成电路,包括:第一收发机和第二收发机,该第一收发机和第二收发机通过信号线执行数据的发送和接收。第一收发机包括:第一终端电路,该第一终端电路包括第一电阻器和第一开关,该第一电阻器被设置在第一电源端子和信号线之间,第一开关控制流过第一电阻器的电流被导通和截止;以及控制电路,该控制电路将第一控制信号输出到第一终端电路,使得当第一收发机接收数据时第一开关被接通,当第一收发机发送数据时第一开关被断开,并且当第一收发机在接收数据之后进一步接收另一数据时,在接收到数据之后的第一预定时段期间第一开关持续接通。
