摘要： A control apparatus for accessing a memory card includes a bus, a detecting circuit, and an adjusting circuit. The bus is regarded as a signal transmission line between the control apparatus and the memory card. The bus has a power signal transmission line for providing the memory card with a power signal. The detecting circuit detects an operating status of the control apparatus and generates an indication signal when the operating status exceeds a predetermined operating range. The adjusting circuit is coupled to the bus and detecting circuit, and is utilized for adjusting a current passing through the power signal transmission line according to the indication signal without closing the power signal transmission line thereby making the operating status operated within the predetermined operating range.
