Parameter
Data Retention
Notes
1.
The relationship between retention, temperature, and the associated reliability level is characterized
separately. Endurance is the guaranteed number of read or write cycles per address that can be
performed while maintaining the specified data retention. It is unlikely to reach this limit for most
applications.
