Question

Why a ROM does not have data inputs?
1. It does not have a WRITE operation
2. Data inputs are integrated with data outputs
3. Data inputs are integrated with address inputs
4. ROM is sequentially accessed

Answer 1

Correct Answer - Option 1 : It does not have a WRITE operation

ROM (Read-only memory):

• It is a type of non-volatile memory used in computers and other electronic devices.
• Data stored in ROM cannot be electronically modified after the manufacturing of the memory device.
• ROM is useful for storing software that is rarely changed during the life of the system also known as firmware.
• Strictly ROM refers to memory that is hard-wired such as a diode matrix or a mask ROM integrated circuit which cannot be electrically changed after manufacturing.
• ROM does not have data inputs because it does not have a WRITE operation.
