Abstract
A data compression method is disclosed. The data compression method is applied to a flash memory device having a flash memory medium. The data compression method includes: reading at least two pieces of cold data in the flash memory medium; compressing the at least two pieces of cold data in the flash medium, so as to obtain at least two pieces of compressed data; splicing the at least two pieces of compressed data, so as to generate at least one write unit; and writing each of the at least one write unit into the flash memory medium.
Claims20
A method of data compression, applied to a flash memory device comprising a flash medium, the method comprising:
- reading at least two pieces of cold data in the flash medium;
- compressing the at least two pieces of cold data in the flash medium to obtain at least two pieces of compressed data;
- concatenating the at least two pieces of compressed data to generate at least one write unit;
- and
- writing each of the at least one write unit into the flash medium.
A flash memory device, comprising:
- a flash medium;
- a data reading module for reading at least two pieces of cold data in the flash medium;
- a data compression module for compressing the at least two pieces of cold data in the flash medium to obtain at least two pieces of compressed data;
- a data reassembly module for concatenating the at least two pieces of compressed data to generate at least one write unit;
- and
- a data writing module for writing each of the at least one write unit into the flash medium.
