Abstract: A method for maintaining a data set includes storing a base copy of the data set in a first non-volatile memory having a first writing speed, storing changes to the data set in a first change data set in a second non-volatile memory having a second writing speed, and generating a current copy of the data set by reading the base copy and the changes. If a threshold number of entries in the first change data set is reached, then part or all of the first change data set is moved into a second change data set in the first non-volatile memory, where the generating step includes reading the second change data set. If a threshold number of entries in the second change data set is reached, then the current copy is generated by reading the base copy and the changes in the first and the second non-volatile memory.

The memory array includes a plurality of pages and a plurality of paired pages, which correspond to the respective pages. The program method includes the following steps. Firstly, a program address command is obtained. Next, whether the program address command corresponding to any one of the paired pages is determined. When the program address command corresponds to a first paired page, which corresponds to a first page among the pages, among the paired pages, data stored in the first page to a non-volatile memory are copied. After that, the first paired page is programmed.

Abstract: A method for programming a non-volatile memory including a plurality of blocks, each block including a plurality of sections, each section including at least one page, and each page including a plurality of memory cells. The method includes checking a current section of the plurality of sections against a damaged section table to determine whether the current section is damaged. The damaged section table records information about whether a section in the memory is good or damaged. The method further includes using the current section for programming if the current section is not damaged.

Abstract: A control method for flash memory based on variable length ECC is provided in the present invention. A first channel of the flash memory is set to have a first ECC with a first length based on the size of data page and the length of first management data; and a second channel of the flash memory is set to have a second ECC with a second length based on the size of data page and the length of second management data. The first ECC and the second ECC are designated with different identification codes respectively, wherein the first length is shorter than the second length.
