Abstract
A method and apparatus for refreshing flash memory are disclosed herein. The method includes allocating a different and increasing sequence number to each of a plurality of physical blocks of the flash memory and storing each of the sequence numbers in connection with each of a corresponding one of the physical blocks in non-volatile memory. A refresh-sequence number equal to the highest sequence number in the non-volatile memory is also stored, and in response to a refresh trigger, data in each of the physical blocks that has a sequence number less than the refresh-sequence number is copied to a corresponding one of a plurality of new physical blocks. A new sequence number is then allocated to each of the new physical blocks.
