Patent ID: 7317434

Claim:
A circuit for an electronic device, wherein the circuit comprises: a select unit comprising a control terminal, a first terminal, and a second terminal, wherein: the control terminal is connected to a first select line; and the first terminal of the select unit is connected to a data line; a data holder unit comprising a first terminal and a second terminal, wherein the first terminal of the data holder unit is connected to the second terminal of the select unit; an electronic component comprising a first electrode and a second electrode, wherein the electronic component is connected to a first power supply line; a transistor comprising a first gate electrode, a first source/drain region, and a second source/drain region, wherein: the first gate electrode is connected to the first terminal of the data holder unit and the second terminal of the select unit; and the first source/drain region is connected to the first electrode of the electronic component and coupled to the second terminal of the data holder unit; the second source/drain region is coupled to a second power supply line; and within the circuit, the transistor is an only transistor having both of its source/drain regions lying in a conduction path between the first and second power supply lines; and a switch comprising a control terminal, a first terminal, and a second terminal, wherein: the control terminal of the switch is coupled to the first select line; and the first terminal of the switch is connected to the first electrode of the electronic component; and the second terminal of the switch is connected to a reference voltage line, wherein the select unit and the switch are configured to turn on at substantially a same time, and the select unit and the switch are configured to turn off at substantially a same time.
