摘要: A termination circuit for a plurality of memories controlled by a controller is provided. The termination circuit includes a plurality of drivers, a plurality of resistors and a plurality of capacitors. Each of the drivers is coupled to the memories via a transmission line. Each of the resistors is coupled to the corresponding driver via the corresponding transmission line. Each of the capacitors is coupled between the corresponding resistor and a reference voltage. The controller is coupled to the memories via the drivers, and the controller provides a specific code to one of the drivers when a quantity of logic “0” and a quantity of logic “1” transmitted to the memories via the transmission line corresponding to the one of the drivers are unbalanced, so as to adjust a termination voltage of the capacitor corresponding to the one of the drivers.
