Model 4200-SCS User’s Manual Section 3: Common Device Characterization Tests
Figure 3-96 shows connections to an array test structure, where one of the four
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). Figure 3-96 allows for pulsing one DUT while performing disturb
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 Figure 3-97.
