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 will 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. Either 4200-
SMUs or 4210-SMUs with SMU preamplifiers removed can be used.
•
Interconnecting cables and adapters, shown in the table below.
•
8 in. lb. torque wrench for tightening the SMA connections.

This configuration permits independent source and measure for each terminal in a typical 4-terminal
floating gate transistor.
