Firmware memory types such as ROM, EPROM, and flash memory are erasable by typical system use.

Firmware memory types such as ROM, EPROM, and flash memory are erasable by typical system use.

• A. False
• B. True
• C. Only for EPROM
• D. Depends on device

Answer: (A)

Understanding how different firmware memory types handle erasure clarifies why that statement isn’t accurate. ROM is written during manufacture and is not erasable by normal operation; it stays fixed unless you replace the component or use a special process. EPROM can be erased, but only with a deliberate, non-standard step (historically UV exposure or a special tool), not through typical device use. Flash memory is designed to be rewritten, but erasing and rewriting are controlled processes performed through a dedicated update sequence or bootloader, not something that happens during ordinary operation. Because none of these memory types are meant to be erased as part of normal system use, the claim is false.
