My basic question is: What is a good alternative to EEPROM chips for external memory on the Arduino Unor R3?
I know that there are EEPROM chips when one would like an external memory chip. It, in fact, seems like this is the standard choice. I am wondering if there are any other good ways to work with external memory. Are there, for example, memory chips that work a bis simpler? Like, a chip that doesn't require any specific libraries in the Arduino?
(I do not have extensive experience working with the Arduino.)
