FLASH存储器又称闪存,它结合了ROM和RAM的长处,不仅具备电子可擦除可编程(EEPROM)的性能,还不会断电丢失数据同时可以快速读取数据。

数据删除不是以单个的字节为单位而是以固定的区块为单位,区块大小一般为256KB到20MB。闪存是电子可擦除只读存储器(EEPROM)的变种,EEPROM与闪存不同的是,它能在字节水平上进行删除和重写而不是按区块擦写,这样闪存就比EEPROM的更新速度快,所以被称为Flash erase EEPROM,或简称为Flash Memory。由于其断电时仍能保存数据,闪存通常被用来保存设置信息,如在电脑的BIOS(基本输入输出程序)、PDA(个人数字助理)、数码相机中保存资料等。另一方面,闪存不像RAM(随机存取存储器)一样以字节为单位改写数据,因此不能取代RAM。
