Electronic device for routing memory address and method of operating thereof

A method of operating an electronic device, the method comprising:

• determining whether an input memory address comprised in a memory command received from a host processor corresponds to one of predetermined designated memory addresses;
• and
• when the input memory address corresponds to one of the designated memory addresses, converting the input memory address into a redirected memory address that is mapped to the corresponding designated memory address, based on mapping information stored in a routing register,
• wherein the mapping information maps each of the designated memory addresses representing a partial area of a memory to a redirected memory address representing another partial area of the memory, and
• the memory command is executed at the converted redirected memory address.

A memory device comprising:

• a routing register configured to store mapping information that maps each of predetermined designated memory addresses representing a first region of a memory to a redirected memory address representing a second other region of the memory;
• and
• a selection logic configured to determine whether an input memory address received in a memory command corresponds to a given address among the designated memory addresses, based on some bits of the input memory address,
• wherein the memory device executes the memory command at the input address when the input address does not correspond to the given address and otherwise executes the memory command at the redirected memory address.
