EPROM

Detailed explanation-1: -To erase and reprogram the EPROM, UV light is required. The light clears the data on the chip and readies it for reprogramming by focusing on a quartz crystal window at the top of the EPROM. This window is transparent, and the silicon chip is visible through it, which permits exposure to UV light during erasure.
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: -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.
Detailed explanation-4: -EPROM (Erasable Programmable Read-Only Memory) is a type of non-volatile memory (meaning that its data is retained even after power is turned off) which can be erased by exposing it to a strong ultraviolet light source for about 20 minutes.
Detailed explanation-5: -A user can erase the data present in EPROM by exposing it to UV (ultraviolet) light.
