Detailed explanation-1: -EPROM (erasable programmable read-only memory) is memory that does not lose its data when the power supply is cut off. The data can be erased and the chip reprogrammed by shining an intense ultraviolet (UV) light through a window designed into the memory chip.
Detailed explanation-2: -Once programmed, an EPROM can be erased by exposing it to strong ultraviolet light source (such as from a mercury-vapor lamp).
Detailed explanation-3: -Electrically-erasable programmable ROM (EEPROM)-Often used in older computer chips and to control BIOS, EEPROM can be erased and reprogrammed several times while enabling the erase and writing of only one location at a time.
Detailed explanation-4: -EPROMs are erased with ultraviolet light.
Detailed explanation-5: -EEPROM (electrically erasable programmable read-only memory) is a user-modifiable ROM. It can be erased and reprogrammed (written to) repeatedly by applying an electrical voltage that is higher than normal.
