A data programming method, a memory storage device and a memory control circuit unit are provided. The method includes presetting a programming mode of a plurality of first type physical erasing units as a first programming mode, and presetting a programming mode of a plurality of second type physical erasing units as a second programming mode. The method also includes obtaining a change parameter according to usage parameters of the first type physical erasing units and the second type physical erasing units. The method further includes determining whether the change parameter matches a first change condition, and if the change parameter matches the first change condition, programming a write-data into the second type physical erasing unit by using the first programming mode.

Data programming method, memory storage device and memory control circuit unit

A memory management method is provided according to an exemplary embodiment of the disclosure. The method includes: receiving a plurality of commands from a host system; counting a newest idle time corresponding to the commands and a past average command-receiving-time-interval corresponding to the commands; and dynamically changing a work mode of a memory storage device from a first work mode to a second work mode if the newest idle time is larger than a first threshold value and the past average command-receiving-time-interval is larger than a second threshold value. Therefore, a power consumption of the memory storage device can be reduced and a work mode of the memory storage device may not be changed too frequently.

A mapping table updating method, a memory control circuit unit and a memory storage device. The method includes: receiving a first data corresponding to a first logical address from a host system; loading a first logical address-physical address mapping table according to the first logical address; sending a command sequence to a rewritable non-volatile memory module; in the process of writing the first data into a first physical programming unit according to the command sequence by a control circuit of the rewritable non-volatile memory module, updating the first logical address-physical address mapping table; and after writing the first data into the first physical programming unit by the control circuit, storing the updated first logical address-physical address table back to the rewritable non-volatile memory module.

Mapping table updating method, memory control circuit unit and memory storage device

The present invention relates to a memory management method, memory control circuit unit, and a memory storage device. The method includes: transmitting temporary data from a buffer memory to a register of a first memory plane; releasing a first storage space of the buffer memory, wherein the first storage space is configured to store the temporary data; performing a first operation to a second memory plane by using the first storage space; and after finishing the first operation performed on the second memory plane, reloading the temporary data from the register of the first memory plane to the first storage space of the buffer memory, wherein operations performed on the first memory plane and the second memory plane are asynchronous operations.

Memory management method for buffer memory, and memory control circuit unit and memory storage device using the same

A mapping table loading method and a memory storage apparatus are provided. The method includes: receiving a plurality of first read commands comprising a plurality of first logical units; executing a first logical-physical mapping table pre-loading operation to read a plurality of mapping information corresponding to the first logical units in a logical-physical mapping table from a rewritable non-volatile memory module to a first buffer area of a buffer memory according to a first executing sequence of the first read commands if the first logical units are not continuous logical addresses; and reading data belonging to the first logical units from physical erasing units to the first buffer area according to the mapping information of the first logical units, and replacing the mapping information of the first logical units in the first buffer area by the data belonging to the first logical units.

Mapping table loading method and memory storage apparatus

A data writing method for writing data into a physical erasing unit and a memory controller and a memory storage apparatus using the data writing method are provided. The method includes dividing the data into a plurality of information frames in a unit of one physical programming unit. The method also includes writing the information frames in sequence into at least one physical programming unit constituted by memory cells disposed on at least one first word line and programming the storage state of memory cells disposed on at least one second word line following the first word line to an auxiliary pattern. Accordingly, the method effectively prevents data stored in the physical erasing unit, which is not full of data, from being lost due to a high temperature.
