    Abstract: A memory card system and related write method are disclosed. The method includes receiving a write request for a predetermined page; performing a write operation on a first log block that corresponds to a first data block including the page; receiving an update request for the page; and performing a write operation on a second log block that corresponds to the first data block. The memory card system includes: at least one non-volatile memory including a data block and a log block for updating the data block; and a memory controller controlling an operation of the non-volatile memory. During a write operation for a predetermined page, the controller controls writing of a first log block corresponding to a first data block including the predetermined page, and controls writing of a second log block during an update operation of the predetermined page.

    Abstract: Provided is a memory card device. The memory card device includes a flash memory and a controller. The flash memory includes a boot area storing boot data, and a user area storing user data. The controller accesses the boot area or the user area according to an external command. Boot data can be stored in a memory card integrated in an electronic device. Also, when a host requests an access to boot data/user data stored in the memory card, the boot data/user data can be accessed under control of the controller.
