In EEPROM, not RAM and yes the "location" is standard. It must be standard in order for payment to work across many devices/shops/cards/banks. I believe the documentation at http://www.emvco.com/cgi_bin/detailspec.pl?id=5 should provide most everything you need to know, though it's not terribly simple. Expect retrieving the data from the card to take you a week or more of focused work, depending on your skill level. If you do it, though, it would be a great piece of work to publish as open source.
