摘要： The invention discloses a memory card control chip. The memory card control chip comprises a clock generator, a first memory card interface, and a control circuit. The clock generator generates a first clock signal and a second clock signal. The second clock signal is a spread spectrum clock signal. The first memory card interface is coupled to the clock generator and comprises a first clock signal pin and a plurality of first data signal pins. The first memory card interface is connected to a first memory card to be a data transmission interface of the first memory card. The first clock signal pin transmits the second clock signal. The control circuit is coupled to the first memory card interface and receives the first clock signal for performing the data accessing of the first memory card.
