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.
