Abstract
A power circuit is adapted for providing a programming voltage to an electronic fuse circuit, and includes a pass transistor of a P-type metal-oxide-semiconductor transistor, a buffer circuit, and a bulk voltage control circuit. The pass transistor includes a bulk electrode, a gate electrode, a first source/drain electrode receiving a system high voltage, and a second source/drain electrode connected to a bit line. The buffer circuit provides a control voltage to the gate electrode of the pass transistor. The pass transistor is turned on during a programming operation and turned off during a reading operation. The bulk voltage control circuit independently provides a bulk voltage to the bulk electrode. A last-stage buffer of the buffer circuit is also activated by the bulk voltage to control the pass transistor during the reading operation of the electronic fuse circuit. A method for providing power to an electronic fuse circuit is also provided.
