Vt_wrt shift of 200 mV after 10k cycles
I_read decrease of 2.5 uA after 10kcycles (- 7 to 9 %)
No big difference between bit0 and bit 7 in terms of Vt or current variations Using the coefficients
4.3.4.2 Cell retention
Purpose:
To extrapolate cell life duration at 125°C from bake measurements at high temperature.
Test parameters:
Lot:
9T0930
Temperature: 250°C and 200°C
Duration:
92 hours
Lifetime Prediction:
The equation used to describe memory cell retention is:
DVt (V) = A * (t[h])^m * exp (-1.05eV/kT[K])
Results :
56.8k cell - 9t0930 (#24/25)
y = 0,2138Ln(x) - 2,3118
y = 0,2211Ln(x) - 4,8026
