Abstract
The present disclosure provides an electronic device that comprises a memory and a controller. The memory includes a first memory location and a second memory location, which are configured to store data in an alternate manner The controller is configured to write, when connection of a display to the electronic device is detected, extended display identification data (EDID) of the display through a first channel to one of the first and second memory locations, and to enable the EDID of the display to be accessible to hosts through second channels.

An electronic device, comprising:
- a memory including a first memory location and a second memory location, which are configured to store data in an alternate manner;
- and
- a controller configured to write, when connection of a display to the electronic device is detected, extended display identification data (EDID) of the display through a first channel to one of the first and second memory locations, and to enable the EDID of the display to be accessible to hosts through second channels.
An electronic device, comprising:
- a memory including a first memory location and a second memory location, which are configured to store data in an alternate manner;
- a first control unit to write extended display identification data (EDID) of a display to one of the first and second memory locations when connection of the display to the electronic device is detected;
- second control units each corresponding to one of multiple hosts, and being configured to allow the corresponding one host to read the EDID of the display connected to the electronic device;
- and
- a processor to set a first pointer to point to one of the first and second memory locations where the most recently written EDID is stored.
A system, comprising:
- a first electronic device including:
- a first memory;
- and
- a first controller including a first control unit to write EDID of a first display to a first memory location of the first memory, and a second control unit to allow a first host to read the EDID of the first display;
- a second electronic device including:
- a second memory;
- and
- a second controller including a first control unit to write EDID of a second display to a first memory location of the second memory, and a second control unit to allow a second host to read the EDID of the second display;
- and
- a communication interface between the first and second electronic devices to allow the first electronic device to send the EDID of the first display to the second electronic device, and allow the second electronic device to send the EDID of the second display to the first electronic device.
