Memory card controller and host device including the same
An interface selection unit physically determines whether or not a memory card is compatible with a first transfer mode, based on the result of signal exchange with the memory card via a first interface unit, to select a first interface unit or a second interface unit. If the second interface unit is selected, a memory card control unit performs an initialization process to cause the memory card to be accessible via the second interface unit, and thereafter, logically determines whether or not the memory card is compatible with the first transfer mode, based on information read from the memory card.
