Abstract
A flash memory control technology with power recovery capability, by which command sequence information is generated for write data that is requested to be written into a flash memory. A random access memory is allocated for temporary storage of the write data and the command sequence information. The write data is uploaded from the random access memory onto a run-time write block between physical blocks of the flash memory with the command sequence information corresponding thereto. During a power recovery process of a data storage device that is equipped with the flash memory, the run-time write block is checked and, according to the command sequence information that has been uploaded onto the run-time write block, the write data in the run-time write block and later in a command sequence than lost data is abandoned.
