Abstract
A data storage device with flash memory and a flash memory control method are disclosed, in which the flash memory includes multi-level cells (MLCs) and single-level cells (SLCs). A microcontroller is configured to establish a first physical-to-logical address mapping table (FH table) in a random access memory (RAM) for a first run-time write block containing MLCs. The microcontroller is further configured to establish a second FH table in the RAM for a second run-time write block containing SLCs. When data that was previously stored in the first run-time write block with un-uploaded mapping information in the first FH table is updated into the second run-time write block, the microcontroller is configured to update a logical-to-physical address mapping table (HF table) in accordance with the first FH table. The HF table is provided within the flash memory.
