Abstract: A block management method, a memory control circuit unit and a memory storage apparatus for managing a plurality of physical blocks are provided. The method includes reading user data from a first physical block among physical blocks to obtain a plurality of parameters; inputting the parameters corresponding to the first physical block into a machine learning based block recognizer to group the first physical block into a first block group or a second block group according to an output result of the machine learning based block recognizer; establishing a first and second block mapping tables; mapping logical addresses of the first and second block mapping tables to the physical blocks belonging to the first and second block groups. The parameters may comprise at least one of a read busy time parameter, an error bit position parameter and a storage retention parameter. A machine learning operation may be performed using first and second test physical blocks, and corresponding parameters, as training data. A usage status may be determined according to the parameters, and blocks with a usage status of good may be used first to evenly use all the physical blocks.

Abstract: A method for programming data is provided for a memory storage device having a rewritable non-volatile memory module and a buffer memory. The method includes receiving a plurality of data including a first-type data and at least one second-type data, and a size of the first-type data is smaller than a data size threshold. The method includes temporarily storing the plurality of data into the buffer memory, and programming the first-type data and at least one part of the at least one second-type data stored in the buffer memory into a physical program unit set if it is determined that the plurality of data are complied with a predetermined condition. The method includes obtaining writing statuses of the first-type data and the at least one part of the at least one second-type data at the same time.
