Title: DATA PROCESSING METHOD AND APPARATUS, AND FLASH MEMORY DEVICE
Abstract:
A data processing method and apparatus, and a flash memory device. The method comprises: receiving an operation instruction sent by a host, performing an operation on data stored in a flash memory device according to the operation instruction, and determining the volume of the data stored by a user in the flash memory device after the operation (S101); according to the volume of the data stored by the user in the flash memory device after the operation and an interval of a user storage space capacity corresponding to each redundancy level, determining a target redundancy level (S102); according to the target redundancy level and the correlation between each redundancy level and an adjustment parameter, determining a target adjustment parameter (S103); and adjusting the size of the redundancy space capacity of the flash memory device according to the target adjustment parameter (S104). The method and apparatus and the flash memory device can dynamically adjust a redundancy ratio, and the reliability and performance stability of the flash memory device can be improved, thereby prolonging the service life of the flash memory device.
