Abstract: A method of facilitating reliably accessing flash memory is provided. During the write-in process, the present invention utilizes the steps of coding write-in data to generate extra data, and then generating the first error correction code by performing an error-correcting operation on the write-in data and the extra data. Finally, store the N write-in data and the generated K extra data into the data area and the first ECC into the spare area. During read process, the present invention utilizes the steps of reading data from the data area of the target flash-memory page to generate the second ECC, counting with the counter a number of bit differences between the first ECC and the second ECC, and selecting M data from the N write-in data and the K extra data as decoding factors to retrieve the N write-in data. The higher the counter values, the lower the likelihood the corresponding bit is selected to be retrieved.

Abstract: A caching method provides a cashing mechanism between a logical addresses and a flash memory physical addresses. The cashing mechanism involves a search tree which contains a number of internal and external translation nodes. Each external translation node points to a link list of translation units, and each translation unit records a range of logical addresses and the corresponding range of physical addresses, in addition to a version value. By traversing the search tree to reach a translation unit, the physical address of a target logical address can be determined in an efficient manner. The version value of the translation unit can be used to determine the space taken up for storing the mapping of the logical and physical addresses should be released for reuse.
