Apparatus and method for establishing data transfer mode through identification of card insertion

An apparatus for establishing a data transfer mode through the identification of the insertion of a multimedia card, the apparatus comprising;

• an assignment operation voltage propriety requester that requests the multimedia card to indicate the propriety of an assignment operation voltage that a card driver assigns as an operation voltage of the multimedia card in consideration of power distribution to an entire system including the apparatus;
• an assignment card address transmitter that receives a response to the request of the assignment operation voltage propriety requester and if the response indicates the propriety of the assignment operation voltage, transmits to the multimedia card an assignment card address that the card driver arbitrarily assigns as a relative address of the multimedia card;
• and
• a data transfer mode establisher that receives predetermined card identification information set by the multimedia card and transmits the card identification information to the card driver to establish the data transfer mode in which data is read or written according to a command of the card driver.

An apparatus for establishing a data transfer mode through the identification of the insertion of a secure digital card, the apparatus comprising:

• an assignment operation voltage propriety requester that requests the secure digital card to indicate the propriety of an assignment operation voltage that a card driver assigns as an operation voltage of the secure digital card in consideration of power distribution to the whole of the apparatus;
• an assignment card address receiver that receives a response to the request of the assignment operation voltage propriety requester and if the response indicates the propriety of the assignment operation voltage, receives an assignment card address that the secure digital card arbitrarily assigns as a relative address of the secure digital card;
• and
• a data transfer mode establisher that receives predetermined card identification information set by the secure digital card and transmits the card identification information to the card driver to establish the data transfer mode in which data is read or written according to a command of the card driver.

A method of establishing a data transfer mode through the identification of the insertion of a card, the method comprising:

• (a) identifying whether a card is inserted;
• (b) if the insertion of the card is identified, receiving predetermined card assignment information from a card driver;
• and
• (c) establishing the data transfer mode for the card based on the card assignment information.

A method of establishing a data transfer mode through the identification of the insertion of a multimedia card, the method comprising:

• (a) requesting the multimedia card to indicate the propriety of an assignment operation voltage that a card driver assigns as an operation voltage of the multimedia card in consideration of power distribution to an entire system;
• (b) receiving a response to the request and if the response indicates the propriety of the assignment operation voltage, transmitting to the multimedia card an assignment card address that the card driver arbitrarily assigns as a relative address of the multimedia card;
• and
• (c) receiving predetermined card identification information set by the multimedia card and transmitting the card identification information to the card driver to establish the data transfer mode in which data is read or written according to a command of the card driver.

A method of establishing a data transfer mode through the identification of the insertion of a secure digital card, the method comprising:

• (a) requesting the secure digital card to indicate the propriety of an assignment operation voltage that a card driver assigns as an operation of the secure digital card in consideration of power distribution to an entire system;
• (b) receiving a response to the request and if the response indicates the propriety of the assignment operation voltage, receiving an assignment card address that the secure digital card arbitrarily assigns as a relative address of the secure digital card;
• and
• (c) receiving predetermined card identification information set by the secure digital card and transmitting the card identification information to the card driver to establish the data transfer mode in which data is read or written according to a command of the card driver.

A register of a controller for controlling a card, which establishes a data transfer mode through the identification of the insertion of a card, the register comprising:

• an assignment operation voltage storage unit that stores an assignment operation voltage;
• an assignment card address storage unit that stores an assignment card address;
• a set operation voltage storage unit that stores a set operation voltage;
• and
• a set card address storage unit that stores a set card address.
