Abstract: The invention introduces a method for garbage collection, performed by a processing unit, including at least the following steps: executing instructions of a GC (garbage collection) process to direct a first access interface to read data from a storage unit, collect good data from the read data and direct the first access interface to program the good data into a spare block of the storage unit. During the GC process, each time that a timer has counted to a time period, the processing unit directs a second access interface to clock a portion of data requested by a host device out to the host device and resets the timer.

Abstract: A data storage device is provided. The data storage device includes a flash memory and a controller. The flash memory includes a plurality of blocks. Each block includes a plurality of pages. when the data storage device is resumed from a power-off event, the controller selects a first block which was written last before the power-off event among the plurality of blocks and writes data of a plurality of first pages of the first block into a plurality of second pages of the first block.

Abstract: For single-level cell flash memories and multi-level cell flash memories, different operations can be performed according to their stability when an abnormal status is terminated. Specifically, for the multi-level cell flash memories, when the abnormal status is terminated, a now physical block is used to proceed with write operation, and the previous physical block(s) would not be written any more. On the contrary, for the single-level cell flash memories, when the abnormal status is terminated, the controller needs to perform corresponding operations on the last physical page of the previous physical block(s).

Abstract: A non-volatile memory device is provided. The non-volatile memory device includes a non-volatile memory, a connection interface, and a controller. The non-volatile memory is divided into a plurality of physical blocks. Each physical block is divided into a plurality of physical pages. The connection interface is connected to a host. The controller is connected to the connection interface. When the controller performs a block-reconfiguration operation, the controller re-adjusts a position in the physical blocks where data is disposed to obtain a usable physical block. Movement of one portion of the data related to the block-reconfiguration operation is performed when the controller operations an initial operation. Movement of another portion of the data related to the block-reconfiguration operation is performed when the controller processes a read command from the host.
