Abstract: A memory operation method, comprising: when a first super block of a memory device is a open block (or in programming state), obtaining a first read count of one of a plurality of first memory blocks in the first super block, wherein the first read count is a number of times that data of one of the first memory blocks is read out; determining whether the first read count is larger than a first threshold; and when the first read count is larger than the first threshold, moving a part of the data in the first super block to a safe area in the memory device, wherein the part of the data comprises data in the first memory block.

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.
