A circuit module with improved line load, may comprise a first line, a first switch, a second line, a second switch and a second driver. The first switch may be on and off to conduct and stop conducting between the first line and a first node. The second switch may be on and off to conduct and stop conducting between the second line and the first node. The second driver, coupled to the second line, may be enabled to drive the second line according to a voltage of a second node, and may be disabled to stop driving the second line. The voltage of the second node may be controlled by a voltage of the first node. When the first switch is on, the second switch may be off. When the second switch is off, the second driver may be enabled.
