Abstract

The invention provides a data storage distribution method, a memory storage device and a memory control circuit unit. The method comprises the following steps: detecting a plurality of data writing speeds of a plurality of memory units; determining the initial write-in quantity of each memory unit according to the number of the crystal grains of each memory unit; calculating at least one compensation data volume according to a plurality of data writing speeds and the initial writing volume of each memory unit; and writing write-in data corresponding to the write-in instruction into the plurality of memory units according to the initial write-in amount of each memory unit and the at least one compensation data amount.

Description

technical field [0001] The invention relates to a memory data storage technology, in particular to a data storage allocation method, a memory storage device and a memory control circuit unit. Background technique [0002] Digital cameras, mobile phones, and MP3 players have grown rapidly in recent years, making consumers' demand for storage media also increase rapidly. Since the rewritable non-volatile memory module (for example, flash memory) has the characteristics of data non-volatility, power saving, small size, and no mechanical structure, it is very suitable for built-in Among the various portable multimedia devices listed above. [0003] With the development of technology, rewritable non-volatile memory modules are gradually changing from single-level storage cell (Single Level Cell, SLC) NAND flash memory modules (that is, flash memory modules that can store 1 bit in one storage unit) Developed into flash memory modules that include memory cells that can store more...
