US 2010/0138594 A1 · FLASH MEMORY DATA READ/WRITE PROCESSING METHOD

Abstract

A flash memory data read/write processing method is provided. The method includes the following steps. An encoding process is performed on the data to be written so that a number of a specific value in the encoded data is reduced compared with that in the original data, and the encoded data is written into a flash memory chip. The encoded data in the flash memory chip is read out, then a decoding process corresponding to the encoding process in Step 1 is performed on the read data, and finally, the decoded data is output. This method may reduce the consumption of a flash memory chip due to writing and erasing operations, thereby prolonging the operating life span of the flash memory chip. This method may also increase the efficiency of writing and erasing operations, reduce the operating time, as well as reduce the power consumption of flash memory operations.

Dependent claims

A flash memory data read/write processing method, comprising:

producing encoded data by performing an encoding process on input data to be written, the input data including a first number of data of a specific value and the encoded data including a second number of data of the specific value, the second number being reduced compared with the first number;
writing the encoded data into a flash memory chip;
reading out the encoded data from the flash memory chip;
producing decoded data by performing a decoding process, corresponding to the encoding process, on the read data;
and
outputting the decoded data.
