Abstract
A plurality of devices under test are each subject to a body bias voltage during burn-in testing. The body bias voltage reduces leakage current associated with the devices under test. A test controller can access a store of information including leakage current as a function of body bias voltage and can select a body bias voltage that corresponds to the minimum leakage current in the store of information. A voltage supply coupled to the test controller can provide the body bias voltage corresponding to the minimum leakage current to the devices under test during the burn-in testing.
