摘要
A flash memory control technique with high reliability is provided. A flash memory controller provides a volatile storage area for temporary storage of logical-to-physical address mapping data between a host and a flash memory as well as error detection codes encoded from the logical-to-physical address mapping data. When reading from the volatile storage area, the microcontroller of the flash memory controller is configured to perform an error detection procedure based on the error detection codes. The microcontroller is further configured to restore the logical-to-physical address mapping data in the volatile storage area based on a backup of the logical-to-physical address mapping data.
