Abstract:
A memory card controller coupled to a host device includes a processing circuit which is used for reading card specific data from a flash memory of a memory card to store the card specific data in a register wherein a multiply parameter and a basic capacity are marked in the card specific data and used for sending the card specific data to the host device to make the host device calculate a maximum capacity of the memory card according to the multiply parameter and the basic capacity marked in the card specific data.
