Electronic device supporting writeback skipping and method of operating the same

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

• checking whether data stored in one or more memory areas, among a plurality of memory areas included in a memory, is useless data;
• and
• transmitting indication information associated with the one or more memory areas to the memory, based on the checking of the useless data,
• wherein
• the indicator information is used to skip a writeback for the one or more memory areas.

An electronic device comprising:

• a first memory;
• a processor connected to the first memory and configured to execute at least one instruction;
• and
• a second memory,
• wherein
• the processor executes the at least one instruction to transmit indicator information to the memory, wherein the indicator information identifies one or more memory areas, among a plurality of memory areas included in the first memory, where useless data is stored, and
• the first memory skips a writeback to the second memory from the one or more memory areas, in response to the indication information.
