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 one sec array erase time. This is a

typical time for one embedded erase operation.

4. Not 100% tested.
