Advantage of EEPROM over EPROM:
c) EEPROM does not require UV light for erasing.
Explanation:
EEPROM (Electrically Erasable Programmable ROM) and EPROM (Erasable Programmable ROM) are both types of non-volatile memory that can be electrically programmed and erased. However, there is a significant advantage that EEPROM has over EPROM.
1. Erasing Method:
- EEPROM: EEPROM can be electrically erased, which means that the data stored in it can be erased using electrical signals. This erasing process does not require the use of UV (Ultraviolet) light.
- EPROM: EPROM, on the other hand, requires exposure to UV light for erasing. The EPROM chip has a quartz window on top that allows UV light to penetrate and erase the stored data. This process can be time-consuming and inconvenient as it requires the chip to be removed from the circuit and exposed to UV light.
2. Ease of Use:
- EEPROM: The electrical erasing method of EEPROM makes it much more convenient and user-friendly. The erasing process can be performed while the chip is still in the circuit, without the need for any additional equipment or exposure to UV light.
- EPROM: In contrast, EPROM requires additional steps to erase the data. The chip needs to be physically removed from the circuit, exposed to UV light for a specified duration, and then reinstalled. This process can be time-consuming and prone to errors if not done correctly.
3. Flexibility:
- EEPROM: The electrical erasing method of EEPROM allows for individual byte or word erasing. This means that specific data can be erased without affecting the rest of the stored information. It provides more flexibility in terms of modifying or updating data.
- EPROM: In EPROM, the entire chip needs to be erased, which means that all the stored data is erased simultaneously. This lack of flexibility makes EPROM less suitable for applications that require frequent updates or modifications.
In conclusion, the main advantage of EEPROM over EPROM is that EEPROM does not require UV light for erasing. The electrical erasing method of EEPROM makes it more convenient, user-friendly, and flexible compared to EPROM, which requires physical removal from the circuit and exposure to UV light for erasing the data.

EEPROM can be electrically erased without the need for UV light, which is required for erasing EPROM. This makes EEPROM more convenient for reprogramming.
