Sample Application Programs
Flash EEPROM Test
Stress setup le for write pulse of NOR type.
Stress setup for write pulse of NOR type is stored in \NORWRT.STR" le on
provided diskette. As described previously, if you use your own setup le
with a dierent le name, change line 2010.
In the NORWRT.STR le, the following is set up.You can modify these
settings in the NORWRT.STR le or your own le:
 PGUs
Unit Period Width Delay

SMU2 (Source) 0V 100 mA
SMU4 (Substrate) 0V 100 mA
Stress setup le for erase pulse of NOR type.
Stress setup for erase pulse is stored on \NORERS
.STR" le on provided
diskette. As described previously, if you use your own setup le with a
dierent le name, change line 2020.
In the NORERS.STR le, the following is set up.You can modify these settings
in the NORERS.STR le or your own le:
 Constant source setup
Unit Source Compliance
SMU2 (Source)

11 V 100 mA
SMU4 (Substrate) 0V 100 mA
1 Erase pulse source
 Erase pulse width
Pulse width of erase pulse is specied as stress DURATION and set to 20ms.
