ABSTRACT:
An apparatus processes data using an external memory. In the apparatus, an external memory power supply provides power to the external memory. An external memory insertion detector detects insertion/removal of the external memory, and continues to detect an inserted state of the external memory when the power provided from the external memory power supply is cut off in the inserted state of the external memory. A first controller provides power to the external memory by controlling the external memory power supply, when the external memory is in use, and cuts off the power provided to the external memory by controlling the external memory power supply, when the external memory is not in use, generates a data list by detecting data from the external memory, and processes normal data in the data stored in the external memory. A second controller processes video data in the data stored in the external memory.
