Semiconductor testing device and method of operating the same

A plurality of devices for testing, connected in series using one or more redistribution layers (RDLs), are used to perform a semiconductor device test on a plurality of dies. As a result, the semiconductor device test may support thousands of gross dies per wafer or greater (e.g., 10,000 dies or greater). Furthermore, the RDL(s) may be removed after use. In some implementations, the devices for testing corresponding to the dies may execute the semiconductor device test sequentially. Accordingly, test data may be generated and may include a bit sequence, where a first bit in the bit sequence indicates an overall outcome for the test and one or more subsequent bits in the bit sequence indicate respective outcomes for each semiconductor dies or for each line of the semiconductor device test.
