Abstract: A memory management method, a memory storage device, and a memory control circuit unit are provided. The memory management method includes: obtaining a first weight value corresponding to a first command in a command queue, wherein the command queue is used to store at least one command to be executed; obtaining a second weight value corresponding to at least one second command being executed; and in response to a sum of the first weight value and the second weight value being greater than a base value, delaying an execution of the first command.

Abstract: A command transmitting method, a memory control circuit unit and a memory storage device are provided. The method includes: transmitting a plurality of command sequences and a state read command sequence to a memory interface coupled to a rewritable non-volatile memory module; and storing the plurality of command sequences by the memory interface, and transmitting the state read command sequence to the rewritable non-volatile memory module.

Abstract: A writing method, a memory controller and a memory storage device are provided. The writing method includes steps of: configuring logical addresses to map to part of physical programming units in a storage area, wherein at least one of the physical programming units stores a valid data; transmitting a first write command for writing data having a first data length to at least one of the physical programming units; receiving a status signal; and selecting a spare physical erasing unit and copying the valid data having a second data length to the spare physical erasing unit, after transmitting the first write command and before receiving the status signal, wherein the first data length is not greater than the second data length. Therefore, it prevents a host system from waiting too long when writing data.

Abstract: A method of recording mapping information for a rewritable non-volatile memory module is provided. The method includes configuring a plurality of logical addresses, establishing at least one logical address mapping table, and storing the at least one logical address mapping table into the rewritable non-volatile memory module. The method also includes receiving data to be stored into a plurality of continuous logical addresses from a host system, writing the data into a plurality of physical programming units, updating mapping relations between the continuous logical addresses and the physical programming units in a corresponding logical address mapping table loaded to a buffer memory, storing a continuous mapping table in the buffer memory, and recording a continuous mapping record corresponding to the continuous logical addresses in the continuous mapping table.
