Abstract
An accessing apparatus capable of reducing power consumption and an accessing method thereof are provided. The accessing method is applied in the accessing apparatus and a host. Firstly, the accessing apparatus is enabled to transmit an external data with the host according to an external clock, and transmit an internal data corresponding to the external data inside the accessing apparatus according to an internal clock. Next, the frequency of the external clock is detected. Then, the frequency of the internal clock is adjusted to a corresponding frequency according to the frequency of the external clock. Lastly, the internal data is transmitted between a buffer and a memory unit of the accessing apparatus by using an internal clock whose frequency equals the corresponding frequency.
