The content of the eeprom specifies everything about the module - size, bank format, timings etc.
I think it's a JEDEC standard.
There is some info on the Micron website - have a look at the datasheets of their SIMMs
You would probably need to tweak the eeprom data if moving chips between SIMMs
It's a standard I2C EEPROM - the addresses are set by the slot number so the ssytem can see what is
in each physical slot.
