Abstract
An environmental tester for memory modules has an environmental chamber for heating the memory modules being tested. One side of the chamber is a backplane. The memory modules are inserted into sockets on module motherboards, which are inserted into motherboard sockets on the backplane. On the other side of the backplane, card sockets receive pattern-generator cards that are outside the environmental chamber but electrically connected to the module motherboards through the backplane. The pattern-generator cards contain pattern-generators that generate address, data, and control signals that exercise the memory modules. The pattern-generator cards can be cooled while the memory modules in the environmental chamber are heated. Pattern-generator cards can be removed for repair and module motherboards can be removed for inserting new memory modules for testing.
