A memory card and a control chip capable of supporting various voltage supplies and a method of supporting voltages are discussed. The memory card includes a flash memory and a control chip for controlling the flash memory, and the control chip has a voltage regulator, a pad power supplier, a core controller and an output circuit. The voltage regulator transforms an external working voltage into a working voltage. The pad power supplier receives the external working voltage and adjusts a level of the external working voltage to output a pad working voltage according to an operating mode. The core controller receives the working voltage to work and generates a control signal. The output circuit receives the control signal and outputs a memory control signal according to a level of the pad working voltage. The control chip controls a flash memory with the memory control signal.
