Abstract
A flash memory system that uses repeated writing of the data to achieve stable storage, is adapted for efficient cache flushing operations by utilizing a part of the non-volatile flash memory array as a designated buffer for the data, in which data integrity is retained until all repeat writing thereof is complete. Repeated writing is carried out from the designated buffer directly to the final storage locations in the flash memory array, for example using simple internal copy back operations.
