Abstract: A data storage device waking up from a sleep mode rapidly is disclosed. The data storage device uses a controller to operate a non-volatile memory. The controller has a microprocessor and a volatile memory. The microprocessor loads boot code from the non-volatile memory to a not-always-on area of the volatile memory according to a script loaded on an always-on area of the volatile memory. The microprocessor executes the boot code loaded on the not-always-on area to load an in-system program from the non-volatile memory to the not-always-on area for execution of the in-system program. The script loaded on the always-on area is loaded from the non-volatile memory, and the non-volatile memory is searched to load the script to the always-on area in response to powering on a data storage device containing the non-volatile memory from a power-off state.

Abstract: The data storage method includes selecting one of a plurality of blocks in a flash memory as an active block; dividing the active block into a plurality of virtual blocks; selecting and accessing one of the virtual blocks; and maintaining a mapping table corresponding to the selected virtual block. The mapping table records mapping information between a plurality of logical addresses and a plurality of physical addresses of the selected virtual block.

Abstract: A data storage device is provided. The data storage includes: a flash memory, a dynamic random access memory (DRAM), and a memory controller. The flash memory stores a logical-to-physical mapping (L2P) table that is divided into a plurality of group-mapping (G2P) tables, and includes a first logical unit number (LUN) and a second LUN that are respectively controlled by a first chip enable (CE) signal and a second CE signal. The memory controller receives a write command from a host, and forms super page data using logical pages of data in the write command. The memory controller reads one of the group-mapping tables from the first LUN or the second LUN to the DRAM after sequentially enabling the first CE signal and second CE signal to write a first portion and a second portion of the super page data to the first LUN and the second LUN.
