ABSTRACT:
A method of refreshing flash memory data in a flash disk card (1) including a flash memory (4) to which data can be written by electrical operations, and an ECC circuit (11) which detects an error of the flash memory data and subsequently corrects the error when the flash memory data stored in the flash memory (4) are read. Hereupon, the method includes the step of reading the whole flash memory data stored in the flash memory (4) by a MPU (6) in the flash disk card (1), when an initialization processing of the flash disk card (1) is carried on after an electrical power has been supplied from an electrical power source to the flash disk card (1). Thus, the reading step is performed as a part of the initialization processing. Further, the method includes the step of rewriting corrected data to the flash memory (4) by the MPU (6) when an error is detected and subsequently corrected by the ECC circuit (11) for the flash memory data read out of the flash memory (4).
