is it possible to write a variable to the arduino chip its self?

just wondering if it is possible to write information such as a few ints to the arduino's chip itself. i want to do this to keep certain settings the way they were left in case of a power failure. so far all i want to do is an array of 5 ints.

if this is possible how can i do it?

thanks as always for the help!

That is what EEPROM is for.

do you mean i should invest in an eeprom chip for my project or the arduino chip has the functionality of an eeprom?

i guess i should have noted im using the uno R3, and plan on just using the chip its self in the final project not the entire developer board.

The Arduino chip as a section that is an EEPROM, and library to read/write from that section.

thanks for the help, i have found the eeprom finctionality of the arduino. seems rather straight foward. been having issues with the site on chrome for some reason. works fine on FF though....

any ways thanks again!
