Abstract: A control method for a multi-channel non-volatile memory is shown. When reading a read target on the non-volatile memory, the controller increases the read count of the monitored unit to which the read target belongs and, based on the read count, determines whether to move data of the monitored unit covering the read target to a safe space to deal with reading interference. The monitored unit is smaller than a cross-channel management unit in read-count group. The controller accesses a parallel accessing space of the non-volatile memory in parallel through all of the channels, and allocates the parallel accessing space based on the cross-channel management unit.

Abstract: A data storage device includes a flash memory and a controller. The flash memory includes a plurality of chips, each of the chips includes a plurality of pages, the pages are arranged to assemble into a super block, the pages of the super block are numbered 0˜X from top to bottom of the super block, the pages with number 0˜Y−1 constitute a data area, and the pages with numbers Y˜X constitute a RAID parity area. The controller corrects data of the data area according to data of the RAID parity area when the data in the data area cannot be successfully read.

Abstract: A method for managing a plurality of data blocks of a data storage device includes steps of: reading a plurality of data pages in the data blocks which having valid data; updating a plurality of access counts of the data pages in the data blocks; determining whether an access count of the data block is greater than or equal to an access count threshold, wherein the access count of the data block is selected from one of the access counts of the data pages therein; and when the determination is positive, storing data in the data block into a spare data block of the data blocks. The access count threshold is updated when an erase count of the data block is determined to be greater than or equal to an erase count threshold. A method of data management for a data storage device is also provided.

Abstract: A data storage method includes steps of: selecting an active block to store data from a host; determining whether a power drop/loss event has occurred; when it is determined that a power drop/loss event has occurred, recording an index of the active block and an index of a last data-containing page in the active block; generating a primary F2H mapping table; and writing the primary F2H mapping table, the index of the active block and the index of the last data-containing page into a designated block. A data storage device and a data recovery program are also provided.
