  • Patent number: 6751760
    Abstract: A method and a system for performing memory repair analysis are provided. A merge circuit is connected between test storage device of semiconductor testing equipment and pre-analysis storage device of repair analysis apparatus. Prior to memory repair analysis process, data from a plurality of functional tests are merged as a functional test data with addresses of fail bits by the merge circuit, then stored in pre-analysis storage device for analyzing. Therefore, test time is reduced and test efficiency is improved.
    Type: Grant

  • Publication number: 20030101388
    Abstract: A system and a method for avoiding waiting repair analysis for a semiconductor testing equipment are disclosed. The semiconductor testing equipment directly executes next functional test after transferring previous test data regardless of if repair analysis is completed or not. A repair analysis apparatus has a pre-analysis storage device with a larger capacity than the test storage device of the semiconductor testing equipment for off-line repair analysis, so that the semiconductor test is efficiently improved.
