Question

Consider the following statements regarding PROM/EPROM:

1. The erasable programmable ROM using ultraviolet erasing is known as EPROM.

2. The ROM that makes use of the electrical voltage for erasing is known as electrically alterable ROM.

3. A PROM can be programmed many times after fabrication.

Which of the above statements are correct?

1. 1 and 2 only
2. 1 and 3 only
3. 1, 2 and 3
4. 2 and 3 only
5.

Answer 1

Correct Answer - Option 1 : 1 and 2 only

Analyzing each statement

Statement 1 :- Erasable progrommable ROM is a read only memory that can be erased and reused erasure is caused by shining an intense UV light.

Hence, Statement 1 is correct.

Statement 2 :- Statement 2 is also correct.

Statement 3 :- it is incorrect because PROM can only be programmed once during fabrication after fabrication it cannot be re-programmed.
