- Option 2: Main memory is faster than secondary memory but slower than registers.

- This statement is correct. Main memory is indeed faster than secondary storage like HDDs or SSDs but is slower than CPU registers.

- Option 3: They are made up of semiconductors.

- This statement is correct. Main memory is typically constructed from semiconductor materials.

- Option 4: All are correct
