FLASH存储器又(yòu)称闪存，它结合了ROM和RAM的長(cháng)处，不仅具(jù)备電(diàn)子可(kě)擦除可(kě)编程（EEPROM）的性能(néng)，还不会断電(diàn)丢失数据同时可(kě)以快速读取数据。

数据删除不是以单个的字节為(wèi)单位而是以固定的區(qū)块為(wèi)单位，區(qū)块大小(xiǎo)一般為(wèi)256KB到20MB。闪存是電(diàn)子可(kě)擦除只读存储器(EEPROM)的变种，EEPROM与闪存不同的是，它能(néng)在字节水平上进行删除和重写而不是按區(qū)块擦写，这样闪存就比EEPROM的更新(xīn)速度快，所以被称為(wèi)Flash erase EEPROM，或简称為(wèi)Flash Memory。由于其断電(diàn)时仍能(néng)保存数据，闪存通常被用(yòng)来保存设置信息，如在電(diàn)脑的BIOS(基本输入输出程序)、PDA(个人数字助理(lǐ))、数码相机中(zhōng)保存资料等。另一方面，闪存不像RAM(随机存取存储器)一样以字节為(wèi)单位改写数据，因此不能(néng)取代RAM。
