Popis: We investigated the data retention mechanism of metal-oxide nitride oxide silicon (MONOS) flash memory. We developed a data retention model that is based on the thermionic emissions and the simple estimation method with a long lifetime and a wide temperature range. The estimated retention results from using the new method were in good agreement with the measurement retention results from more than 6 years and within a temperature range from 150–450°C. The MONOS memory with split-gate (SG-MONOS) we created has a 20-yr lifetime at more than 200°C.
