ABSTRACT:
A memory controller for reducing a time to create an address management table during initialization of a memory card. The memory controller includes a read-write memory for temporarily storing the address management table and a second memory controller for writing, in a nonvolatile memory, an address management table temporarily stored in the read-write memory. The second memory controller also writes address range specifying information that specifies an address range, when a data writing destination is changed from a first address range to a second address range. The memory controller includes an address management table generator for reading distributed management information used for managing a state of at least one physical block included in the destination address range specified by the address range specifying information during initialization, and to generate the address management table based on the distributed management information.
