Method and electronic device for recognizing touch

An electronic device comprising:

• a housing including a first surface and a second surface opposite the first surface;
• a display exposed through the first surface and interposed between the first surface and the second surface;
• a touch panel interposed between the display and the first surface or coupled to the display;
• a display driver integrated circuit (DDI) electrically connected to the display and including a first memory;
• a touch controller integrated circuit (IC) electrically connected to the touch panel and including a second memory;
• a processor electrically connected to the DDI and the touch controller IC;
• and
• a nonvolatile memory electrically connected to the processor,
• wherein the nonvolatile memory stores instructions that, when executed, cause the processor to:
• store, in the first memory, first data related to a graphic user interface (GUI) to be displayed in a first portion of the display while the processor is deactivated or in a sleep state,
• store second data associated with a second portion of the touch panel in the second memory, wherein the second portion of the touch panel at least partially overlaps the first portion of the display, and wherein the second portion of the touch panel is activated while a remaining area of the touch panel outside the second portion is deactivated, and
• enter the sleep state after storing the first data in the first memory and the second data in the second memory.
