Abstract
A test device includes a power supply circuit that is configured to supply an input voltage through a power voltage pin to a memory device under test, and a test controller, which is configured to: (i) transmit a command signal to the memory device, (ii) measure a first current flowing to the memory device through the power voltage pin at a first time point after transmitting the command signal, (iii) measure a second current flowing to the memory device through the power voltage pin at a second time point, which is different from the first time point, and (iv) compare the measured first current to the measured second current to thereby determine whether the memory device has a defect therein.
