A nonvolatile memory and a mapping control apparatus and method of the same are disclosed, whereby block state information is changed depending on an operation performed by the nonvolatile memory to efficiently access a flash memory. The mapping control apparatus comprises a nonvolatile memory that has an area divided into blocks and stores block state information representing the state of written data, and a control unit that determines a block for a data operation through the block state information when the data operation is performed in the nonvolatile memory, and that updates the block state information depending on the result of the performed data operation.
