( computer science) a read-only memory chip that can be erased by ultraviolet light and programmed again with new data. 只读存储芯片可以被紫外线辐射擦去并且可以输入新的数据。
PXE most commonly involves booting a computer from firmware i.e., a read-only memory or programmable ROM chip rather than from magnetic media. 最常见的PXE是从固件、即只读式存储器或可编程ROM芯片,而不是从磁介质引导计算机。
Electrically erasable programmable read-only memory ( EEPROM) is mainly applied to information memory such as intelligentized IC card, single chip microcomputer, etc. It is divided into parallel and serial. 电可擦除可编程只读存储器(EEPROM)主要应用于智能IC卡,微型计算机等各种需要对信息存取的场合。EEPROM分为并行和串行两种。
