Notes
1
This parameter is periodically sampled and not 100% tested.
2
The relationship between /CE and /WE determines if a /CE- or /WE-controlled write occurs. There is no timing
specification associated with this relationship.

Notes
1. Data retention is specified at 85
°
C.
2. Endurance is the guaranteed number of read- or write-cycles per address that can be performed while maintaining
the specified data retention. It should be impossible to reach this limit for most applications.
