Patent ID: 7560947

Claim:
Automatic test equipment (ATE) comprising: a computer system configured to provide control signals to a testing device; and a testing device configured to test a semiconductor device in accordance with the control signals, the testing device comprising a pin for providing voltage to the semiconductor device, the testing device comprising a driver configured to drive the voltage to the pin, wherein the driver comprises: a first driver circuit configured to provide at least part of a programming signal to the semiconductor device via a first impedance path; and a second driver circuit configured to provide at least part of the programming signal to the semiconductor device via a second impedance path, the programming signal for programming the semiconductor device, the programming signal having a higher voltage level than a test signal provided to test the semiconductor device, and the second impedance path having a lower impedance than the first impedance path; wherein the second driver circuit is configured to activate when the first driver circuit provides at least part of the programming signal, and wherein the second driver circuit has a slower turn-on time than the first driver circuit.
