摘要： A mapping algorithm for efficient access to a flash memory, wherein block state information that is changed through logical operations required by a processor is written in the flash memory according to a predetermined state transition algorithm and the changed information is referred to upon read/write operations. A mapping control apparatus for a flash memory according to the present invention includes a flash memory having regions divided on a block basis and containing block state information indicating the state of each block, each block including a predetermined number of sectors; and a processor for determining a sector on which a predetermined logical operation is to be performed based on the block state information and updating the block state information according to a predetermined state transition algorithm, when the logical operation is required for the flash memory.

摘要： 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.
