Manner and system null in order to try support the big

摘要

Without violating to the specification of device, in addition optimizing efficiency, the flash memory system, bigger page than operating system data sector size the system and method in order to make that the flash which it has (2) & the device which are supported possible. According to this invention, entry logic of the flash memory system, during sector entry processing, does not consider with PPP restriction and the page size of the device and the te does not become. PPP, the when, simply it should write new data, in addition allotting the new page, produces effect on the decision whether it should copy the data which exists from the time before to this new page of. According to this invention, when the page includes the sector of one or more, standard it substitutes the software, to physical address, but after discovering address, inspecting the page which includes that address, it counts the number of other sectors inside the same page which already includes the data. Then, it decides whether you write the sector to inside calculation physical address, or to inside the new page the sector entry, simultaneously, you copy the existing sector which it adjoins in this new page as an option.
