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 μs consists of 10 μs program pulse and 4 μs 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 1 sec array erase time. This is a typical
time for one embedded erase operation.
4. Not 100% tested.
