摘要： A data storage device utilized for accessing boot data includes a flash memory, a controller and a RAM. The flash memory includes several blocks, and each block includes several pages. The controller is coupled to the flash memory and the RAM. The controller receives a write command from a host and determines whether the data of the write command is system data or normal data. If the data to be written is system data, the controller transmits a confirm message to the host after the system data has been completely stored on the data storage device.

摘要： A data storage device includes a memory device and a memory controller. The memory controller selects a predetermined memory block to receive data and records multiple logical addresses in a first mapping table. The first mapping table records which logical page the data stored in each physical page of the predetermined memory block is directed to. A bit table is stored in a buffer memory and includes multiple fields. Each field records a bit value. When the memory controller writes data of a logical page that corresponds to a first logical address into the predetermined memory block, the memory controller records the first logical address in the first mapping table, converts the first logical address according to a predetermined function to generate a first field index of the bit table and sets the bit value corresponding to the first field index as a first value in the bit table.

摘要： 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 operates 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.

摘要： 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.

摘要： A data storage device includes a memory device and a memory controller. The memory controller selects a predetermined memory device to receive data and accordingly records multiple logical addresses in a first mapping table. The first mapping table records which logical page the data stored in each physical page of the predetermined memory block is directed to. When the predetermined memory block is full, the memory controller edits a second mapping table and a third mapping table according to the first mapping table. The second mapping table corresponds to multiple logical pages and records which memory block and which physical page is the data of each logical page stored in. The third mapping table corresponds to the physical pages of the predetermined memory block and indicates whether each physical page is a valid page or an invalid page.
