What the difference between EEPROM and ROM?

Post by javaABC » Sun Mar 18, 2018 11:07 pm

Hi everyone. I have a question: What the difference between EEPROM and ROM? Are the card OS store in EEPROM or in ROM? And what about algorithms in EEPROM or ROM?

Can someone tell me?

EEPROM (also E2PROM) stands for electrically erasable programmable read-only memory and is a type of non-volatile memory,EEPROMs can be programmed and erased in-circuit, by applying special programming signals.
Read-only memory (ROM) is a type of non-volatile memory, ROM cannot be changed after manufacture, so it is mainly used to store firmware.
The card os can store in EEPROM, also store in ROM. The algorithm is the same in EEPROM and ROM .
