A software redundancy method for improving reliability of data storage of EEPROM

摘要: 针对嵌入式微控制器系统中EEPROM存储的数据在受到干扰时可能丢失或发生变化的问题，分析了EEPROM存储数据丢失的原因，提出了一种提高EEPROM数据存储可靠性的软件冗余方法。该方法通过分区存储和CRC校验，降低了数据在一定时间内被全部破坏的可能性，增强了部分数据被破坏后的恢复能力。应用表明，该方法能够有效提高EEPROM数据存储的可靠性。

Abstract: For problems that data stored in EEPROM of embedded microcontroller system would loss or change because of interference, the paper analyzes causes of loss or damage of stored data in EEPROM, and proposed a software redundant method for improving reliability of data storage of EEPROM. The method uses partition storage and CRC checksum technology to reduce possibility of collapse of the whole data in a given time, which improves recovery ability of EEPROM after stored data was partly damaged. The application showed the method can effectively improve reliability of data storage of EEPROM.
