Question

EPROM contents can be erased by exposing it to
1. Ultraviolet rays.
2. Infrared rays
3. Burst of microwaves
4. Intense head radiations

Answer 1

Correct Answer - Option 1 : Ultraviolet rays.

Concept:

• EPROM stands for erasable programmable read only memory.
• EPROM is non volatile kind of memory.
• If ultraviolet rays are exposing (Mercury –vapor light) to EPROM chip, then this chip will releases stored charge. The stored content in that EPROM chip will be lost or erased.

Hence option 1 is the correct answer.
