Abstract
An integrated circuit formed using a semiconductor substrate may include a logic circuit and a switch circuit, whereby the logic circuit operates at a first power supply voltage and the switch circuit operates at a second power supply voltage that is greater than the first power supply voltage. The logic circuit may be formed within a first triple well structure within the semiconductor substrate and is supplied with a first bias voltage. The switch circuit may be formed within a second triple well structure that is electrically isolated from the first triple well structure within the semiconductor substrate and is supplied with a second bias voltage. The switch circuit may receive a control signal that controls the first bias voltage and the second power supply voltage to turn off a transistor in the logic circuit during a programming operation of the integrated circuit.
