Abstract:
1. An environmental tester for memory modules comprising: a backplane forming one side of an environmental chamber; motherboard sockets mounted on a first side of the backplane; removable module motherboards for insertion into the motherboard sockets; a plurality of memory-module sockets mounted on each of the removable module motherboards, the plurality of memory module sockets for receiving memory modules for environmental testing in the environmental tester; card sockets mounted on a second side of the backplane; removable pattern-generator cards for insertion into the card sockets; and a pattern-generator on each of the removable pattern-generator cards for generating address, data, and control signals to write data to a plurality of memory locations on memory chips on the memory modules inserted into the memory-module sockets on the removable module motherboards, whereby memory modules are tested within the environmental chamber by pattern-generators on removable pattern-generator cards outside the environmental chamber that are separated by the backplane that forms one side of the environmental chamber.
