Use this semiconductor calculation for first-order device, material, fabrication, interconnect, packaging, or reliability estimates when every coefficient and unit convention is known.

Threshold field (MV/cm)

Required number in MV/cm. Field required to switch the resistive state.

Oxide thickness (nm)

Required number in nm. Switching oxide thickness.

The cited overview of Resistive random-access memory supplies background for the terminology and domain context used by this tool.^[1]

Compute the memristor threshold switching voltage from the switching field in MV/cm and oxide thickness in nanometres. Inputs are interpreted exactly in the displayed units and the calculation returns the following fields without presentation rounding.

Switching voltage (V)

Returned number in V. Applied voltage that reaches the switching field.

• Material composition, geometry, process history, temperature, electric field, bias, interfaces, parasitics, and fitted parameter ranges can invalidate a compact semiconductor model.
• Threshold field must be at least 5e-324.
• Oxide thickness must be at least 5e-324.
• Use finite inputs in the displayed units, preserve source measurements and assumptions, and independently verify consequential decisions.

Compare the estimate with measured process data, current device documentation, and a higher-fidelity circuit, field, thermal, quantum, or TCAD model when the decision requires it.
