Abstract
An electronic apparatus having read-only memories (ROMs), wherein a second ROM having a region capable of being read with addresses common to a part of an address region of a first ROM can be connected. Reading from addresses included within the address region of the first ROM is performed from the second ROM when the addresses are also included within the address region of the second ROM, and from the first ROM for other cases. Furthermore, the first ROM can be replaced with a third ROM, to which addresses not overlapped with those of the second ROM are assigned.
