Abstract
To measure an inner temperature of a chamber included in a test handler, self-refresh currents of semiconductor memory devices under test are measured. The semiconductor memory devices are disposed in the chamber and have a function of linear temperature compensated self-refresh (Li-TCSR). Local temperature values are generated based on the self-refresh currents, where each local temperature value indicates a temperature near the corresponding semiconductor memory device of the semiconductor memory devices under test.
