The present disclosure includes various method, device, and system embodiments for isolation circuits. One such isolation circuit embodiment includes: a first transistor configured for connection to a supply voltage via a first terminal; a register connected to the first transistor; a second transistor in parallel with a resistor, wherein the second transistor is configured for connection to the first terminal, with a gate of the second transistor configured for connection to an output of the register; and wherein the second transistor is configured for connection to a second terminal, the second transistor having a state that depends on a status of the register.

Isolation circuit

The present disclosure includes various method, device, and system embodiments for isolation circuits. One such isolation circuit embodiment includes: a first transistor having its source connected to a first terminal, wherein the first terminal connects a supply voltage to the source of the first transistor; a register connected to the drain of the first transistor; and a second transistor in parallel with a resistor, the gate of the second transistor is connected to an output of the register and a source of the second transistor is connected to the first terminal. In various embodiments, the drain of the second transistor is connected to a second terminal and the state of the second transistor depends on whether the register is loaded.

A method and system for testing a plurality of semiconductor dice on a semiconductor wafer during burn-in includes forming a plurality of semiconductor dice with each die including an integrated circuit and built-in self stress circuitry coupled thereto. The built-in self stress circuitry includes contacts coupled thereto that are configured for probing by a probe card on a burn-in tester. The built-in self stress circuitry, through an interface with the integrated circuit, generates signals for exercising the operation of the integrated circuit during burn-in testing. Each of the plurality of semiconductor dice on the semiconductor wafer are individually controllable by the burn-in tester.
