MRAM Retention Time
Néel–Arrhenius MRAM retention estimate τ=τ₀ exp(Δ) from attempt time and dimensionless thermal-stability factor.
Description
Néel–Arrhenius MRAM retention estimate τ=τ₀ exp(Δ) from attempt time and dimensionless thermal-stability factor.
MRAM Retention Time is a focused tool for the following task. Néel–Arrhenius MRAM retention estimate τ=τ₀ exp(Δ) from attempt time and dimensionless thermal-stability factor. It reports Retention Seconds from the values you provide rather than inventing measurements, coefficients, or professional judgment that are not part of the input.
When to use MRAM Retention Time
Use this semiconductor calculation for first-order device, material, fabrication, interconnect, packaging, or reliability estimates when every coefficient and unit convention is known.
- Attempt Seconds (s)
- Required number in s.
- Stability Factor
- Required number.

How MRAM Retention Time works
Néel–Arrhenius MRAM retention estimate τ=τ₀ exp(Δ) from attempt time and dimensionless thermal-stability factor. Inputs are interpreted exactly in the displayed units and the calculation returns the following fields without presentation rounding.
- Retention Seconds (s)
- Returned number in s.
Limitations and assumptions
- Material composition, geometry, process history, temperature, electric field, bias, interfaces, parasitics, and fitted parameter ranges can invalidate a compact semiconductor model.
- Attempt Seconds must be at least 0.
- Stability Factor must be at least 0.
- Use finite inputs in the displayed units, preserve source measurements and assumptions, and independently verify consequential decisions.
Alternative or Complementary approaches
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.

Estimate DRAM retention time from cell capacitance, allowable refresh voltage drop, and leakage current. Formula: t_ret [s] = (C [fF]·1e-15·ΔV [V])/(I_leak [fA]·1e-15) = C·ΔV/I_leak, derived from charge Q=C·ΔV leaking at rate I_leak. Inputs: C>0 fF, ΔV>0 V, I_leak>0 fA. Output: t_ret>0 s. Assumes constant leakage, no refresh overhead, and that the cell holds charge C·V until droop ΔV.
