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

Rated Cycles

Required integer.

Used Cycles

Required integer.

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

Remaining nominal PCM program/erase cycles from rated endurance and recorded cycle count. Inputs are interpreted exactly in the displayed units and the calculation returns the following fields without presentation rounding.

Remaining Cycles

Returned integer.

• Material composition, geometry, process history, temperature, electric field, bias, interfaces, parasitics, and fitted parameter ranges can invalidate a compact semiconductor model.
• Rated Cycles must be at least 0.
• Used Cycles must be at least 0.
• 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.

• Flash Endurance Cycles Calculator

  Calculate rated flash program-erase cycles remaining and the percentage consumed from completed and rated cycle counts.

• ALD Growth Per Cycle Calculator

  Divide the total ALD film thickness (final minus initial) by the number of cycles to get the average growth per cycle.

• Dislocation Density from Etch Pits

  Convert a counted number of etch pits on a measured field area into a dislocation density per square centimeter. Formula: D [1/cm²] = N / (A [µm²]·1e-8), where 1 µm² = 1e-8 cm², N is integer pit count ≥0, A>0 µm². Output D≥0 1/cm²; D=0 when N=0. Assumes each pit corresponds to one threading dislocation, uniform distribution, and accurate field area measurement.
