Red face Memory Question

So I completely disconnected both front and rear + & - for 2weeks , to reset all modules but when I reconnect them codes were still there and had no effect on any of the preset memories , my question is what would happen if winterized the car and took out both batteries for several months, would everything still stay in the memory long with the codes ???
