Section 6: Clarius

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.

Recommended interconnect parts for flash memory testing

SMA tee, female – male – female

LEMO triaxial to SMA adapter

3-slot male triaxial to female BNC adapter

SMA male to BNC female adapter

10.8 cm (4.25 in.) white SMA cables

20.3 cm (8 in.) white SMA cables

2 m (6.6 ft) white SMA cables

1.5 m (5 ft) BNC cable

This configuration permits independent source and measure for each terminal in a typical 4-terminal

floating gate transistor.
