Abstract
With the aid of a storage unit for storing EDID, a memory unit is merely provided power by a bus power while a related power source is turned off, and power leakage is prevented since possible paths of the power leakage are blocked by reverse biasing of related elements of the storage unit. A storage module including a plurality of the designed storage units have same operations and performance as those of the designed storage unit.
Claims19
A storage unit for storing extended display identification data (EDID) comprising:
- a signal source connector;
- a first diode having an input terminal coupled to a power terminal of the signal source connector;
- a second diode having an output terminal coupled to an output terminal of the first diode, and an input terminal coupled to a first power source;
- a switch having a first output terminal coupled to the output terminal of the second diode, and an input terminal coupled to a second power source;
- a memory unit having a first terminal coupled to the first output terminal of the switch for storing EDID information;
- and
- a display data channel (DDC) having a first terminal coupled to a signal terminal of the signal source connector, and a second terminal coupled to a second terminal of the memory unit.
