Abstract
A data processing apparatus and method for a flash memory, which make it easy to determine whether data stored in the flash memory is valid, are provided. The data processing apparatus includes a user request unit which issues a request for performing a data operation on a flash memory using a predetermined logical address, a conversion unit which converts the logical address into a physical address, and a control unit which performs the data operation on the physical address and writes inverted data obtained by inverting error correction code (ECC) corresponding to data used in the data operation to a region indicating whether the ECC is erroneous.
