Data retention4
4 Typical data retention values are based on intrinsic capability of the technology measured at high temperature and de-rated
to 25
°C using the Arrhenius equation. For additional information on how Freescale defines typical data retention, please refer
to Engineering Bulletin EB618/D, Typical Data Retention for Nonvolatile Memory.
