AC CHARACTERISTICS
Erase/Program Operations (V
Notes:
1. Not 100% tested.
2. Asynchronous mode allows the Asynchronous program operation only. Synchronous mode allows both Asynchronous and Synchronous program
3. In asynchronous program operation timing, addresses are latched on the falling edge of WE# or rising edge of AVD#. In synchronous program
4. See the “Erase and Programming Performance” section for more information.
5. Does not include the preprogramming time.
