Program Customization
This section describes how to customize program for your own application.
Subprogram \Test setting".
In this subprogram, you may need to customize the following:
 Name of setup les.
If you want to use your own measurement or stress setup les, store the
les on diskette, then modify the le names on the following lines:
Measurement setup le name for Vth measurement.
1980 Vth_file$="ROMVTH.MES" ! Vth Measurement Setup File Name
Stress setup le name for write pulse.
1990 Wrt_file$="NORWRT.STR" ! Write Stress Setup File Name
Stress setup le name for erase pulse.
2000 Ers_file$="NORERS.STR" ! Erase Stress Setup File Name
 File name for saving measurement results.
Following two lines create following le name for saving measurement
results: time .DAT .To change this le name, modify these lines:
2010 Save_file$=TIME$(TIMEDATE) ! File Name for saving measurement results
2020 Save_file$=Save_file$[1,2]&Save_file$[4,5]&Save_file$[7,7]&".DAT"
 Number of times to repeat measurement (FOR loop of Main Program)
Following line species how many times to measure Vth during stress.
2030 Meas_points=16 ! Number of times to repeat Measurement
 Stress pulse count data.
For example,if Meas_points=4 , a total of ten write/erase pulses are
forced, and Vth is measured after 1st, 2nd, 5th, and 10th pulse
.
2060 Str_num: ! ! Stress Pulse Count data
2070 DATA 1, 2, 5
2080 DATA 10, 20, 50
2090 DATA 100, 200, 500
2100 DATA 1000, 2000, 5000
2110 DATA 10000, 20000, 50000
2120 DATA 100000, 200000, 500000
2130 DATA 1000000
