The figure shows a useful map, which is not the map out of reset. After reset the map is:
$0000 - $03FF: Register Space
$0800 - $3FFF: 14K RAM
$0000 - $0FFF: 4K EEPROM (1k $0400 - $07FF visible, $0000 - $03FF and $0800 - $0FFF are not visible)
Various possibilities to make more of the EEPROM fully visible are available, one of them is shown above
