Assuming an ambient temperature of 55°C and a junction temperature rise of 15°C.
Chi-squared 60% estimations used to calculate the failure rate with only zero reject
Thermal Acceleration Factor is calculated from the Arrhenius equation
E  1 1  
AF = exp  A  -  

where:
EA =The Activation Energy of the defect mechanism.
k = Boltzmann's constant = 8.62x10-5 eV/Kelvin.
T1 is the junction temperature of the device under stress and T2 is the junction temperature of the device
at use conditions.

FLASH MEMORY ENDURANCE AND DATA RETENTION
Units1 cycled 90000 times or less have an expected data retention lifetime equal to or greater than 20 years2.
For units cycled 100000 times or more, the data retention cummulative failure rate over time is defined below:
