Explanation:

EPROM (UV Erasable Programmable Read Only Memory) is a special type of ROM that is pro- grammed electrically and yet is erasable under UV light. The EPROM device is programmed by forcing an electrical charge on a small piece of polysilicon material (called the floating gate) located in the memory cell.

Answer 2

Answer:

An EPROM (rarely EROM), or erasable programmable read-only memory, is a type of programmable read-only memory (PROM) chip that retains its data when its power supply is switched off. ... Once programmed, an EPROM can be erased by exposing it to strong ultraviolet light source (such as from a mercury-vapor lamp).
