Which type of non-volatile memory is electrically erasable and programmable?

The characteristic feature of electrically erasable and programmable non-volatile memory is most concisely represented by EEPROM (Electrically Erasable Programmable Read-Only Memory). EEPROM allows data to be written and erased electrically, which means that it can be modified without requiring physical removal from the system or a complete power cycle. This capability is particularly advantageous in scenarios where frequent updates to the stored information are needed, as it allows for selective rewriting of data without needing to erase the entire memory block, unlike some other non-volatile memory types.

Flash memory, while also electrically erasable and programmable, is structured differently and typically allows for erasure in larger blocks rather than individual bytes, which differentiates its operational mode from that of EEPROM. RAM (Random Access Memory) is a volatile memory type that loses its contents when power is turned off, and while it can be quick and efficient for temporary data storage during operation, it does not retain information once the device is powered down. Intermediate storage is not a standard classification in terms of memory types and does not specifically refer to a recognized memory architecture like the others mentioned. Thus, EEPROM stands out as the correct choice since it meets the criteria of being non-volatile and allowing for individual data updates through electrical means
