Patent ID: 7398444

Claim:
A method for testing a semiconductor device, comprising: communicating test input data to the semiconductor device; performing a test of the semiconductor device using the test input data to obtain test output data, the test comprising: outputting the test input data by an output driver of the semiconductor device; and inputting the output test input data into an input driver of the semiconductor device, thereby generating test output data from the output test input data, wherein the output driver is signal-connected to a first data pad, the first data pad is signal-connected to a first external data contact, the first external data contact is signal-connected to a second external data contact, the second external data contact is signal-connected to a second data pad, and the second data pad is signal connected to the input driver, during the test to enable the test input data to be simultaneously output from and input to the semiconductor device; and creating a data test result from the test output data.
