EEPROM: is a type of non-volatile memory used in computers and other electronic devices to store small amounts of data that must be saved when power is removed. Such as 28F series;EPROM: is a type of memory chip that retains its data when its power supply is switched off; Such as 27 seriesPROM: is a form of digital memory where the setting of each bit is locked by a fuse or antifuse.MARK PROM: is a type of memory that can not erased.
