  • Publication number: 20150058685
    Abstract: A method of testing a semiconductor memory includes generating a logical value of a test pattern through an algorithm pattern generator included in a field programmable gate array. The generated logical value is programmed in a DUT under the control of a DQ signal responding to a DQ enable signal that is generated from automatic test equipment and is then transferred to the field programmable gate array. The programmed logical value is captured from the DUT under the control the DQ signal. The generated logical value is compared with the captured logical value. Whether the DUT is defective is determined according to a result of the comparison. The DQ enable signal is applied to a time point different from a time point when a SYNC clock for synchronizing the automatic test equipment with the field programmable gate array is applied.
