SMU+PG2 channels was split to provide a total of five test signals to provide the
minimum necessary channels for the select pins (Bit Line Select, Bit Lines 1 and
2), to the pulse DUT (circled in blue), and the measure DUTs (circled in dashed
purple).
measurements on the three DUTs labeled Measure. The preferred connection
method for disturb testing, or any testing of a an array DUT, is to add a switch
matrix, as shown in
