Question: what is the difference between flash memory eprom and eeprom?
Answer: An EPROM (Erasable PROM) had a little window on the top, which allowed it to be erased using a UV light. ... EEPROM (Electrically-erasable PROM) made it possible to both program and erase the chip electrically. Flash memory (which is used to store the code in today's microcontrollers) is just a variation of EEPROM .
