Reliability of erasing operation in NOR-Flash memories

WebNOR Flash memory cells are susceptible to degradation due to excessive Program/Erase (P/E) cycling. Worst case, if the number of P/E cycles exceeds the datasheet limit, the flash memory could fail, as the ability of the flash to retain information stored in the memory cells can be degraded over time.
