Abstract
A method for cleaning valid bits in a cache memory is provided. The method includes performing a valid-bit-cleaning process to sequentially clean a valid bit corresponding to each address of the cache memory when an integrated circuit is booted up or enters a working state from a sleep mode. In response to a flash memory controller reading data from a specific address of the flash memory, the method includes notifying the cache memory controller to suspend the valid-bit-cleaning process, and utilizing the cache memory controller to write the data into the specific address of the cache memory and to set the valid bit corresponding to the specific address as valid. In response to the valid bit being set as valid, the method includes reading the data from the specific address of the cache memory, transmitting the data to the processor, and resuming the valid-bit-cleaning process.
