A.3.2 NVM Reliability
The reliability of the NVM blocks is guaranteed by stress test during qualification, constant process
monitors and burn-in to screen early life failures.
The failure rates for data retention and program/erase cycling are specified at the operating conditions
noted.
The program/erase cycle count on the sector is incremented every time a sector or mass erase event is
executed.
Conditions are shown in Table A-4 unless otherwise noted
