Patent number: 11862275Abstract: Systems and methods are provided for testing a Device Under Test (DUT) in its working environment. A control computer is coupled to an air compressor and generates a temperature control signal that is provided to the air compressor to generate an amount of hot air or cold air to set the temperature of the DUT's working environment to a desired test temperature. The control computer also generates at least one test signal that is sent to a hardware test element for testing at least one memory component of the DUT at the desired test temperature and obtaining test results. The control computer analyzes the test results to determine a parameter adjustment for the at least one memory element so that it operates in a stable manner at the test temperature.Type: GrantFiled: March 6, 2020Date of Patent: January 2, 2024Assignee: KINGTIGER TECHNOLOGY (CANADA) INC.Inventors: Bosco Chun Sang Lai, Sunny Lai-Ming Chang, Lawrence Wai Cheung Ho, Eric Sin Kwok Chiu, Simon Shu Man Choi, Arthur Yu Kuen Lam
