Abstract
An internal clock generation circuit includes a delay line in which a plurality of inverter circuits are connected in series. A switch and a capacitor are connected to an output node of each inverter circuit. The switch connected to each inverter circuit is turned on/off individually according to respective control signals. In response to the switch being turned on, the output node of a corresponding inverter circuit and the capacitor are connected, whereby the capacitance of the output node of the corresponding inverter circuit is altered. As a result, the transmission rate of the signal is altered.
