    摘要: A dynamic time sequence control device and its method for a word matching circuit. The word matching circuit includes a first switch connected between an input voltage and a node to respond to a control signal generated by a pre-charging circuit so that within a pre-charging phase period a current is generated to flow through a capacitor to generate a charging voltage. The node is connected to multiple data memories and matching circuits so that the matching result can be outputted through the node. The dynamic time sequence control device includes a second switch connected between the first switch and the node. A third switch is connected between the data memory and matching circuit and a self time sequence controller has a threshold value to respond to the control signal and to conduct the second switch and turn off the third switch during the pre-charging phase period, meanwhile, it turns off the second switch and conducts the third switch when the charging voltage is detected to be larger than threshold value. The self time sequence controller detects the output voltage of the node and outputs the data matching result during a value-acquisition phase period.
