摘　　要：EEPROM(Electrically Erasable Programmable Read-Only Memory)是一种广泛应用于电子设备中的非易失性存储器。其主要作用存储参数、记录数据、记录用户使用习惯及使用情况、掉电记忆功能等作用。尽管EEPROM其具有数据保存稳定、可多次擦写等优点,但在实际应用中,EEPROM数据被意外改写的情况时有发生,数据被错误改写后引起电控无法工作等问题。本文将详细介绍EEPROM元器件的基本功能,分析数据被改写的常见原因(硬件、软件、环境等因素),并提出相应的应对方案和改进设计方案,以提高电控系统的可靠性和数据的安全性。Electrically Erasable Programmable Read-Only Memory(EEPROM)is a type of non-volatile memory widely used in electronic devices.Its main function is tostore parameters,record data,record user usage habits and usage,pow-er failure memory function.Although EEPROM has the advantages of stable data preservation and multiple erasability,in practical applications,the EEPROM data is often accidentally rewritten,and the electronic control can not work after the data is wrongly rewritten.This paper will introduce the basic functions of EEPROM components in detail,analyze the common reasons for data rewriting(hardware,software,environment and other factors),and propose corresponding solu-tions and improved design schemes toimprove the reliability of electronic control systemand data security.
