AC Characteristics—Write/Erase/Program Operations
Notes:
1. Read timing characteristics during read/write operations are the same as during read-only operations. Refer to AC
Characteristics for Read Only operations.
2. Embedded Program Operation of 14 s consists of 10 s program pulse and 4 ms write recovery before read. This is the
minimum time for one pass through the programming algorithm.
3. Embedded Erase Operation of 5 sec consists of 4 sec array pre-programming time and one sec array erase time. This is a
typical time for one embedded erase operation.
4. Not 100% tested.
