Sweep Operation 9-25
‘Setup Source Memory Location 100 (Dummy Location) ‘Turn off everything to increase speed.
‘------------------------------------------------------
‘ Using a Dummy Location allows the Source Memory
‘ Sweep to stop testing the DUT as quickly as possible.
‘ This allows the test setup to ensure high yields and
‘ to not waste test time on devices that fail early
‘ in the Source Memory Sweep.
