Memory tester with output of data pertaining to test sample

摘要

The tester transmits a test sample read-out request to a memory (30) and picks-up test sample signals from a data input and output bus (29a) as a reaction to the request the test sample signals are compared with their expectation values in a comparator (34). The output (22,23) has a sample number output for test sample numbers with corresponding data. A memory control (24,26-28) transmits the test sample request as a reaction to pertinent data. The output may be of programmed type. An Independent claim is included for the memory testing process.
