Abstract:
A data access apparatus includes: a flash memory controller; a mirror means; and a flash memory including at least one data region and at least one mirror region. The mirror means copies data to form mirror data to the mirror region when the flash controller writes the data into the data region. The flash memory controller reads the mirror data to replace the data if the flash memory controller determines that the data include error(s) while the data are being read.
