Detailed explanation-1: -A programmed EPROM can retain its data for 10 to 20 years. Some EPROMs can retain data for even longer. The data is retained even when power is cut off and can be retrieved after the power is turned back on, making it a type of non-volatile memory. To erase and reprogram the EPROM, UV light is required.
Detailed explanation-2: -EPROM can be erased by exposing it to ultra-violet light for a duration of up to 40 minutes. Usually, an EPROM eraser achieves this function. During programming, an electrical charge is trapped in an insulated gate region. The charge is retained for more than 10 years because the charge has no leakage path.
Detailed explanation-3: -EPROM (Erasable programmable read-only memory): EPROM is a nonvolatile kind of memory. If ultraviolet rays are exposing (Mercury –vapor light) to the EPROM chip, then this chip will release stored charge. The stored content in that EPROM chip will be lost or erased.
Detailed explanation-4: -A special type of PROM in which the information stored in it can be erased by exposing it to electrical charge at one byte at a time. It is a non volatile memory in which the information stored Is retained even after the power goes off.
Detailed explanation-5: -EPROM, in full erasable programmable read-only memory, form of computer memory that does not lose its content when the power supply is cut off and that can be erased and reused.
