EEPROM（带电可擦写可编程只读存储器）是用户可更改的只读存储器（ROM），其可通过高于普通电压的作用来擦除和重编程（重写）。不像EPROM芯片，EEPROM不需从计算机中取出即可修改。在一个EEPROM中，当计算机在使用的时候可频繁地反复编程，因此EEPROM的寿命是一个很重要的设计考虑参数。EEPROM是一种特殊形式的闪存，其应用通常是个人电脑中的电压来擦写和重编程。-EEPROM (electrically erasable programmable read only memory) is a read-only memory can be changed by the user s (ROM), which can be obtained by higher than normal voltage to erasing and reprogramming (Rewriting). Unlike the EPROM chip, EEPROM does not need to be removed from the computer can modify. In a EEPROM, while computer is in use can be frequently repeated programming, therefore the service life of the EEPROM is a very important design parameters are considered. EEPROM is a special form of flash memory, its application is usually a voltage in a personal computer to erasing and reprogramming.
