Testing flash memory
Clarius includes several projects that you can use to test floating gate transistors (NOR, NAND) and
other types of nonvolatile memory.
To use the flash memory tests, you need:
• Two pulse cards (four pulse channels).
• At least two SMUs. If your system does not include switching, it is best to have four SMUs to
match the number of pulse channels to connect to a three- or four-terminal device. You can use
4200-SMUs, 4201-SMUs, 4210-SMUs, or 4211-SMUs with the SMU preamplifiers removed.
• Interconnecting cables and adapters, shown in the following table.
• 8 in.-lb torque wrench for tightening the SMA connections.
