Measurement setup le for Vth measurement (for NOR type).
Measurement setup for Vth measurement is stored in \ROMVTH.MES" le on
provided diskette. As described previously, if you use your own setup le
with a dierent le name, change line 2000.
In the ROMVTH.MES le, the following is set up.You can modify these
settings in the ROMVTH.MES le or your own le:
Gate voltage sweep setup.
Start voltage Stop voltage Sweep step Compliance
0V 8V 10 mV 1nA
SMU1 is gate voltage source as shown in Figure 6-1 and Figure 6-2.
Constant source setup.

Analysis function for Vth extraction.
In this example, Vth is extracted by moving marker to the point where Id is
1
A, then reading the voltage at that point. Refer to the following user
function and auto-analysis setup:
