Abstract

A data storage device and a flash memory control method with a power recovery design. A microcontroller is configured to allocate a flash memory to provide a first block from the blocks to work as a run-time write block for reception of write data. During a power recovery process due to an unexpected power-off event that interrupted write operations on the first block, the microcontroller is configured to allocate the flash memory to provide a second block from the blocks for complete data recovery of the first block and to replace the first block as the run-time write block.
