Abstract: A method for managing a flash memory device including pages of memory cells is described. The memory device may be erasable at the page level, and the pages may include operative pages for storing operative values and service pages for storing information relating to the erasing of the operative pages. In response to a request to erase selected operative pages, the method may include determining a service page in use among the service pages according to service information stored in the service pages, verifying the presence a service page to be erased, and applying an erasing pulse to each service page to be erased. The method may also include writing an address of the operative pages into the service page in use, erasing the selected operative pages, and writing a completion indication of the erasing of the selected operative pages into the service page in use.
