Which of the following is a type of ROM that can be **electronically erased and reprogrammed multiple times** without removing it from the circuit?

Question

Accepted Answer

**Solution:**

1. **EEPROM (Electrically Erasable Programmable Read-Only Memory)** is a type of ROM that can be erased and reprogrammed multiple times using electrical signals, without needing to remove the chip from the circuit.

2. Unlike **EPROM**, which requires ultraviolet light for erasing data, EEPROM allows in-circuit electrical erasure and reprogramming, making it highly convenient for firmware updates and embedded systems.

3. **PROM (Programmable ROM)** can only be programmed once after manufacturing and cannot be erased or rewritten.

4. **Mask ROM** is programmed permanently during manufacturing and cannot be altered afterward.

Therefore, the correct answer is **EEPROM** as it supports multiple electronic erasures and reprogramming cycles.

**Answer:** EEPROM
